From: Jacob Kiefer <jt...@cornell.edu>
Changed raid_cmd interface to accept le32 mask instead of
u32 and converting internally. Updated existing calls to raid_cmd.
This patch pushes responsibility to the caller to convert
the mask to le32 and opts for a temp local struct instead of
memset/memcpy. This cleans up the code considerably.
Also removed magic numbers.
This patch fixes the following sparse error:
CHECK drivers/staging/rtl8723au/hal/rtl8723a_cmd.c

In v3, opted to change the interface rather than just the internal
code, and removed ugly memcpy/memset. This clears sparse errors
and makes the code more sane.
