ext4: don't print scary messages for allocation failures post-abort
I often get emails containing the "This should not happen!!" message,
conveniently trimmed to remove things like:
sd 0:0:0:0: [sda] Unhandled error code
sd 0:0:0:0: [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_TIMEOUT
sd 0:0:0:0: [sda] CDB: Write(10): 2a 00 03 13 c9 70 00 00 28 00
end_request: I/O error, dev sda, sector 51628400
Aborting journal on device dm-0-8.
EXT4-fs error (device dm-0): ext4_journal_start_sb: Detected aborted journal
EXT4-fs (dm-0): Remounting filesystem read-only
I don't think there is any value to the verbosity if the reason is
due to a filesystem abort; it just obfuscates the root cause.
