net: mana: Fix race on per-CQ variable napi work_done

BugLink: https://bugs.launchpad.net/bugs/2003353

After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be
cleared, and another CPU can start napi thread and access per-CQ variable,
cq->work_done. If the other thread (for example, from busy_poll) sets
it to a value >= budget, this thread will continue to run when it should
stop, and cause memory corruption and panic.

To fix this issue, save the per-CQ work_done variable in a local variable
before napi_complete_done(), so it won't be corrupted by a possible
concurrent thread after napi_complete_done().

Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done
variable race is fixed, so the driver is able to reliably support features
like busy_poll.

UBUNTU: SAUCE: tdx: Drivers: hv: vmbus:: Fix the ARM64 build caused by recent TDX patches

BugLink: https://bugs.launchpad.net/bugs/2002658

Need to declare hv_isolation_type_tdx() for ARM64 as well.

PAGE_KERNEL_NOENC is only defined for x86, so let's still use
PAGE_KERNEL for ARM64.

UBUNTU: SAUCE: tdx: x86/hyperv: Fix serial console interrupts for TDX guests

BugLink: https://bugs.launchpad.net/bugs/2002658

When a TDX guest runs on Hyper-V, the firmware sets the HW_REDUCED flag,
and consequently ttyS0 interrupts can't work. Fix the issue by overriding
x86_init.acpi.reduced_hw_early_init().
