staging: rtl8192e: Remove function rtl92e_update_rx_pkt_timestamp()

Browse Source 
mac_time and last_rx_desc_tsf are only used in
rtl92e_update_rx_pkt_timestamp(). Depending on a condition one is equal
to the other or vice versa. But since those are not used anywhere else
the function rtl92e_update_rx_pkt_timestamp() is just dead code.
