xfs: pass the actual offset and len to allocate to xfs_bmapi_allocate
xfs_bmapi_allocate currently overwrites offset and len when converting
delayed allocations, and duplicates the length cap done for non-delalloc
allocations. Move all that logic into the callers to avoid duplication
and to make the calling conventions more obvious.
