Darrick J. Wong cb41f22df3 xfs: remove infinite loop when reserving free block pool ...

commit 15f04fdc75aaaa1cccb0b8b3af1be290e118a7bc upstream.

[Added wrapper xfs_fdblocks_unavailable() for 5.10.y backport]

Infinite loops in kernel code are scary.  Calls to xfs_reserve_blocks
should be rare (people should just use the defaults!) so we really don't
need to try so hard.  Simplify the logic here by removing the infinite
loop.
