scsi: megaraid_sas: fixup MSIx interrupt setup during resume
Streamline resume workflow by using the same functions for enabling MSIx
interrupts as used during initialisation. Without it the driver might
crash during resume with:
WARNING: CPU: 2 PID: 4306 at ../drivers/pci/msi.c:1303 pci_irq_get_affinity+0x3b/0x90

scsi: megaraid_sas: Use Block layer API to check SCSI device in-flight IO requests
Remove usage of device_busy counter from driver. Instead of device_busy
counter now driver uses 'nr_active' counter of request_queue to get the
number of inflight request for a LUN.

scsi: megaraid_sas: Limit the number of retries for the IOCTLs causing firmware fault
IOCTLs causing firmware fault may end up in failed controller resets and
finally killing the adapter.
This patch fixes this problem as stated below:
In OCR sequence, driver will attempt refiring pended IOCTLs upto two times.
If first two attempts fail, then in third attempt driver will return pended
IOCTLs with EBUSY status to application. These changes are done to ensure
if any of pended IOCTLs is causing firmware fault and resulting into OCR
failure, then in last attempt of OCR driver will refrain firing it to
firmware and saving adapter from being killed due to faulty IOCTL.

scsi: megaraid_sas: Do not set HBA Operational if FW is not in operational state
After issuing a adapter reset, driver blindly used to set adprecovery flag
to OPERATIONAL state. Add a check to see if the FW is operational before
setting the flag and marking reset adapter successful.

scsi: megaraid_sas: Do not kill HBA if JBOD Seqence map or RAID map is disabled
At the time of firmware initialization, if JBOD map or RAID map is not
available, driver can function without these features in a limited
functionality mode.

scsi: megaraid_sas: Update optimal queue depth for SAS and NVMe devices
Ideally, optimal queue depth will be provided by firmware. The driver
defines will be used as a fallback mechanism in case the FW assisted QD is
not supported. The driver defined values provide optimal queue depth for
most of the drives and the workloads, as is learned from the firmware
assisted QD results.
