[PATCH] xfs: fix error code in xfs_iflush_cluster()

[Dan Carpenter <dan.carpenter@oracle.com>]

Originally this function used to always return -EFSCORRUPTED on error
but now we're trying to return more informative error codes.
Unfortunately, there was one error path missed.  If this kmem_alloc()
allocation fails then we need to return -ENOMEM instead of success.

Fixes: f20192991d79 ("xfs: simplify inode flush error handling")
