btrfs: handle memory allocation failure in btrfs_csum_one_bio
[ Upstream commit 806570c0bb7b4847828c22c4934fcf2dc8fc572f ]
Since f8a53bb58ec7 ("btrfs: handle checksum generation in the storage
layer") the failures of btrfs_csum_one_bio() are handled via
bio_end_io().
This means, we can return BLK_STS_RESOURCE from btrfs_csum_one_bio() in
case the allocation of the ordered sums fails.
This also fixes a syzkaller report, where injecting a failure into the
kvzalloc() call results in a BUG_ON().
