iwm3200wifi: remove comparison to WIFI_IF_NTFY_MAX in iwm_ntf_wifi_if_wrapper

drivers/net/wireless/iwmc3200wifi/rx.c: In function 'iwm_ntf_wifi_if_wrapper':
drivers/net/wireless/iwmc3200wifi/rx.c:1198: warning: comparison is always true due to limited range of data type

This is, of course, because the value of WIFI_IF_NTFY_MAX is 0xff and
hdr->oid is a u8.  This is obviously an attempt to verify the range on
an input value, but since it has no effect it can simply be removed.
