softmac: fix wext MLME request reason code endianness

patch 94e10bfb8a7372df3ef2759c9ec2a37de2f24aca in mainline.

The MLME request reason code is host-endian and our passing
it to the low level functions is host-endian as well since
they do the swapping. I noticed that the reason code 768 was
sent (0x300) rather than 3 when wpa_supplicant terminates.
This removes the superfluous cpu_to_le16() call.
