iwlwifi: support "pure 40MHz" in RXON command
Fix the bug when using 11n "pure 40MHz" mode cause uCode crashing by adding support for "pure 40MHz" in RX_ON command flag. the "mode" field (bits 25:26) has value of 0-3 0 = 20 MHz only 1 = 40MHz only 2 = Mixed 3 = Reserved Control Channel ID (bit 22) is valid only in Mixed mode.
