iwlwifi: dbg_ini: set dump bit only when trigger collection is certain
In case the the trigger occurrences is zero or force_restart is set, the
driver sets IWL_FWRT_STATUS_DUMPING without actually scheduling trigger
collection. At this point no other dump collection can be performed.
Solve this by setting IWL_FWRT_STATUS_DUMPING bit only when the driver
is surely going to schedule dump collection
