xfs: simplify xfs_map_blocks by using xfs_iext_lookup_extent directly

Browse source

xfs_bmapi_read adds zero value in xfs_map_blocks.  Replace it with a
direct call to the low-level extent lookup function.

Note that we now always pass a 0 length to the trace points as we ask
for an unspecified len.
