iwlwifi: de-const properly where needed
In order to de-const variables simply casting through (void *) is
not enough: "cast from 'const .. *' to 'void *' drops const qualifier".
Cast through (uintptr_t) as well [1] to make this compile on systems
with more strict requirements.
In addition passing const void *data to dma_map_single() also
drops the (const) qualifier. De-constify on variable on assignment
which may be overwritten later. In either case the (void *) cast
to dma_map_single() is not needed (anymore) either.
[1] See __DECONST() in sys/sys/cdefs.h in FreeBSD
