btrfs: output mirror number for bad metadata
When handling a real world transid mismatch image, it's hard to know
which copy is corrupted, as the error messages just look like this:
BTRFS warning (device dm-3): checksum verify failed on 30408704 wanted 0xcdcdcdcd found 0x3c0adc8e level 0
BTRFS warning (device dm-3): checksum verify failed on 30408704 wanted 0xcdcdcdcd found 0x3c0adc8e level 0
BTRFS warning (device dm-3): checksum verify failed on 30408704 wanted 0xcdcdcdcd found 0x3c0adc8e level 0
BTRFS warning (device dm-3): checksum verify failed on 30408704 wanted 0xcdcdcdcd found 0x3c0adc8e level 0
We don't even know if the retry is caused by btrfs or the VFS retry.
To make things a little easier to read, add mirror number for all
related tree block read errors.
So the above messages would look like this:
BTRFS warning (device dm-3): checksum verify failed on logical 30408704 mirror 1 wanted 0xcdcdcdcd found 0x3c0adc8e level 0
BTRFS warning (device dm-3): checksum verify failed on logical 30408704 mirror 2 wanted 0xcdcdcdcd found 0x3c0adc8e level 0
BTRFS warning (device dm-3): checksum verify failed on logical 30408704 mirror 1 wanted 0xcdcdcdcd found 0x3c0adc8e level 0
BTRFS warning (device dm-3): checksum verify failed on logical 30408704 mirror 2 wanted 0xcdcdcdcd found 0x3c0adc8e level 0
