Subject: [PATCH 09/31] wifi: mwifiex: deduplicate code in
 mwifiex_cmd_tx_rate_cfg()

The code block inside the if/else is the same with just using
pbitmap_rates if non NULL or priv->bitmap_rates otherwise. Deduplicate
the code by picking the correct pointer first and then using it
unconditionally.
