xfs_scrub: separate internal metadata scrub functions

Refactor xfs_scrub_metadata into two functions -- one to make a single
call xfs_check_metadata, and the second retains the loop logic.  The
name is a little easy to confuse with other functions, so rename it to
reflect what it actually does: scrub all internal metadata of a given
class (AG header, AG metadata, FS metadata).  No functional changes.
