mwl8k: fix up AP vs. STA firmware image receive descriptor handling
The receive descriptor ops that are currently marked as being for 8687 only are actually used for all STA firmware images, whereas the receive descriptor ops marked as 8366 are only used on 8366 when an AP firmware image is in use. Rename the receive descriptor ops to reflect this, use the STA ops unconditionally if the firmware image loaded reported the STA ready code, and rename the mwl8k_device_info::rxd_ops member to ap_rxd_ops to indicate that it should only be used if we are running on AP firmware.
