MFC r228817:

Use the correct types when calling the decompression mask function.

There's currently no public code which uses this feature and the
current reference driver doesn't enable this feature at all.
It's possible it was used by a previous version of the driver and
that indeed it should return HAL_STATUS; but at this point I'm
happy to require that they complain and submit a patch.

This was found by LLVM compile-time type checking.
