iwlwifi: Disable -Wformat when building with GCC.

Browse Source 
GCC's -Wformat complains about NULL format strings passed to
iwl_fw_dbg_collect_trig (though the function handles NULL format
strings).  Curious that upstream iwlwifi in Linux is built with GCC
and explicitly opts into this warning via the __printf() attribute.
