xfs: clean up after failed metafile relinking

Once we start a metadir update to link in a file, we have to commit or
cancel it, just like any other operation.  LOLLM pointed out that I
forgot that, so fix it.  This fixes a bug in xfs_repair.

However, in commit e80fbe1ad8eff7, we made xfs_metadir_cancel a static
function within xfs_metadir.c, so we can't just add a xfs_metadir_cancel
call to xfs_dqinode_metadir_link.

Instead, create a new xfs_metadir_link_file helper in xfs_metadir.c that
takes only the xfs_metadir_update object, and handles everything from
start to finish.  This enables us to make xfs_metadir_commit a static
function too.
