If rt2800usb is loaded with nohwcrypt=1, mac80211 takes
care of the crypto with software encryption/decryption
and thus, MFP can be used.
Tested for secured mesh using ath9k_htc and ath9k.

You set MFP feature regardless if actually hwcrypt is disabled or not.
Beside this should not be done in function which is intended to test
if hw crypto is disabled. Please set the future in place where other
hw->flags are set.
Thanks
