The original Realtek provided functions suffered badly from clutter to
accommodate broken operating systems. Lets try this lean and clean
version instead.
v2: Do not use the stack for data passed to usb_control_msg(). This
requires reintroducing the mutex used in the old function. In
addition, get rid of the no longer used 'usb_vendor_req_buf'.
Note that rtl8723au_writeN() remains unlocked, so it can be used
for bulk block transfers without having to retake the mutex for
every write().
