staging: wlan-ng: ensure error return is actually returned

commit 4cc41cbce536876678b35e03c4a8a7bb72c78fa9 upstream.

Currently when the call to prism2sta_ifst fails a netdev_err error
is reported, error return variable result is set to -1 but the
function always returns 0 for success.  Fix this by returning
the error value in variable result rather than 0.

Addresses-Coverity: ("Unused value")
Fixes: 00b3ed168508 ("Staging: add wlan-ng prism2 usb driver")
