wifi: iwlwifi: fw: don't always use FW dump trig

Browse source

commit 045a5b645d upstream.

Since the dump_data (struct iwl_fwrt_dump_data) is a union,
it's not safe to unconditionally access and use the 'trig'
member, it might be 'desc' instead. Access it only if it's
known to be 'trig' rather than 'desc', i.e. if ini-debug
is present.
