bkey_fsck_err() was added as an interface that looks like fsck_err(), but previously all it did was ensure that the appropriate error counter was incremented in the superblock. This is a cleanup and bugfix patch that converts it to a wrapper around fsck_err(). This is needed to fix an issue with the upgrade path to disk_accounting_v3, where the "silent fix" error list now includes bkey_fsck errors; fsck_err() handles this in a unified way, and since we need to change printing of bkey fsck errors from the caller to the inner bkey_fsck_err() calls, this ends up being a pretty big change. Als,, rename .invalid() methods to .validate(), for clarity, while we're changing the function signature anyways (to drop the printbuf argument).
