[PATCH] Improve error stats message

[Diego <diegocg@gmail.com>]

A typical notification of filesystem errors looks like this:

BTRFS error (device sda2): bdev /dev/sda2 errs: wr 0, rd 1, flush 0, corrupt 0, gen 0

The device name is being printed twice. Also, these abbreviatures
feel unnecesary. Make the message look like this instead:

BTRFS error (device sda2): errors: write 0, read 1, flush 0, corrupt 0, generation 0
