Simplify init_backlog function to avoid coverity BAD_SHIFT errors

The init_backlog function determines the power of two sized memory
allocation that would have at least fnum_max elements. Reworked the
code to make it clearer to the coverity analyzer what it is doing.
Rather than overshooting the desired order value and then adjusting it
down by one the while loop has been revised to exit when the order is
the correct value.

Adjust runtime _access_process_vm_ to work with linux 6.5

Linux kernel commit ca5e863233e8f6acd1792fd85d6bc2729a1b2c10
eliminated the vma argument for ‘get_user_pages_remote. For linux 6.5
kernel use the get_user_page_vma_remote function in its place like the
__access_remote_vm function in mm/memory.c of the kernel.
