This routine is empty, thus all calls to it can be removed.

After removing some empty routines in os_dep/osdep_service.c, new routines
become empty. These include rtw_mfree_stainfo(),
_rtw_free_sta_xmit_priv_lock(), and rtw_mfree_recv_priv_lock.

Wrapper routine rtw_modular64() contains only a call to do_div() and
is used once in the code. Remove the wrapper.

This driver contains a number of macros that are intended to do endian
conversion. The first step in getting rid of them is to delete the
ones that are not used.

This driver defines a set of macros that get or set a bitfield in the
RX and TX descriptors. Most of these have been replaced by the appropriate
use of the system macros BIT() or GENMASK().
While reworking these routines, I also fixed camel case variables and
missing spaces. Some comments were also converted to the
drivers/net/wireless preferred format.
