[PATCH v2 6/6] xfs: defer agfl frees from directory op transactions

[Brian Foster <bfoster@redhat.com>]

Directory operations can perform block allocations as entries are
added/removed from directories. Defer AGFL block frees from the
remaining directory operation transactions. This covers the hard
link, remove and rename operations.
