[ovs-dev] [sparc 5/5] test-csum: Avoid "cast increases required alignment of target type" warning.

Casting a character pointer to uint16_t * or uint32_t * provokes this
warning on sparc.  There is no actual problem, because all of the accesses
to data occurs through calls to the get_unaligned_*() functions, so this
commit suppresses the warning by using "void *" as an intermediate type.
