[PATCH 6.6 021/140] xfs: dont use __GFP_RETRY_MAYFAIL in xfs_initialize_perag

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christoph Hellwig <[email protected]>

commit 069cf5e32b700f94c6ac60f6171662bdfb04f325 upstream.

[backport: uses kmem_zalloc instead of kzalloc]

__GFP_RETRY_MAYFAIL increases the likelyhood of allocations to fail,
which isn't really helpful during log recovery.  Remove the flag and
stick to the default GFP_KERNEL policies.
