Nikolay Borisov ac01f26a27 btrfs: handle failure of add_pending_csums ... add_pending_csums was added as part of the new data=ordered implementation in e6dcd2dc9c ("Btrfs: New data=ordered implementation"). Even back then it called the btrfs_csum_file_blocks which can fail but it never bothered handling the failure. In ENOMEM situation this could lead to the filesystem failing to write the checksums for a particular extent and not detect this. On read this could lead to the filesystem erroring out due to crc mismatch. Fix it by propagating failure from add_pending_csums and handling them.
