Hi all,

this (lightly tested) series cleanups the strange mappedbno argument
to various dabuf helpers.  If that argument has a positive value
it is used as xfs_daddr_t to get/read the block, and otherwise
it is overloaded for a flag.  This series splits out the users that
have a xfs_daddr_t to just use the buffer interfaces directly, and
the replaces the magic with a flags argument and one properly
named flag.
