wifi: iwlwifi: debug: fix crash in __iwl_err()
In __iwl_err(), if we rate-limit the message away, then
vaf.va is still NULL-initialized by the time we get to
the tracing code, which then crashes. When it doesn't
get rate-limited out, it's still wrong to reuse the old
args2 that was already printed, which is why we bother
making a copy in the first place.
Assign vaf.va properly to fix this.
