Wong Change the signature of xfs_blockgc_free_quota in preparation for the next few patches. Callers can now pass EOF_FLAGS into the function to control scan parameters; and the function will now pass back any corruption errors seen while scanning, though for our retry loops we'll just try again unconditionally.
