rtlwifi: rtl8188ee: rtl8192com: rtl8192cu: rtl8192ee: rtl8723ae: rtl87323be: rtl8821ae: Use common cmd_send_packet

A locking problem was found in routine _rtl92ee_cmd_send_packet() that led
to system freezes. Upon inspection, several drivers had the same problem;
however, the routines all used the same code. The common code has been
moved into rtlwifi.
