wireless/gs2200m: Fix handling of ioctl except SIOCDENYINETSOCK

When running a dual stack (usrsock daemon and kernel stack),
ioctl requests that should be handled by the kernel stack are being
processed by the usrsock daemon. This causes ifconfig and ifup to fail.
The usrsock daemon that receives an ioctl request that should be
handled by the kernel stack should reply with ENOTTY.
Replying with ENOTTY means that the ioctl request can fall back to the
kernel stack.
