This patch adds a superblock error counter for every distinct fsck error; this means that when analyzing filesystems out in the wild we'll be able to see what sorts of inconsistencies are being found and repair, and hence what bugs to look for. Errors validating bkeys are not yet considered distinct fsck errors, but this patch adds a new helper, bkey_fsck_err(), in order to add distinct error types for them as well.
