Commit 3b011b097c38 ("staging: r8188eu: limit rf register writes to
path a") limits rf register writes by private ioctls to RF_PATH_A.
Apart from private ioctls, the rest of the driver uses only path a.
This patch limits rf register reads by the private ioctl 0x0D, which
calls rtw_wx_read_rf, to path a.
