xfs: cleanup use of the XFS_ALLOC_ flags

Always set XFS_ALLOC_USERDATA for data fork allocations, and check it
in xfs_alloc_is_userdata instead of the current obsfucated check.
Also remove the xfs_alloc_is_userdata and xfs_alloc_allow_busy_reuse
helpers to make the code a little easier to understand.
