Allow drivers to fix an issue when using wpa_supplicant with WEP.

The problem is introduced by the hwcrypto patch. We changed indicator of
the encryption request from the upper layer (i.e. wpa_supplicant):

In the original host based crypto the driver could use: crypt &&
crypt->ops.

In the new hardware based crypto, the driver should use the flags
specified in ieee->sec.encrypt.
