[PATCH] staging: rtl8723au: change typecast to match type returned by htons()

[Chris Ruffin <cmruffin@gmail.com>]

Using a u16 pointer typecast for a result from htons() results in the following warning from sparse:

drivers/staging/rtl8723au/core/rtw_xmit.c:1279:36: warning: incorrect type in assignment (different base types)
drivers/staging/rtl8723au/core/rtw_xmit.c:1279:36:    expected unsigned short [unsigned] [short] [usertype] <noident>
drivers/staging/rtl8723au/core/rtw_xmit.c:1279:36:    got restricted __be16 [usertype] <noident>

This patch fixes the issue by using an endian-specific typecast
that will always match the type returned by htons().
