xfs: use xfs_alloc_vextent_start_bno() where appropriate
Change obvious callers of single AG allocation to use
xfs_alloc_vextent_start_bno(). Callers no long need to specify
XFS_ALLOCTYPE_START_BNO, and so the type can be driven inward and
removed.
While doing this, also pass the allocation target fsb as a parameter
rather than encoding it in args->fsbno.
