From: Sara Sharon <[email protected]> iwl_fw_dbg_collect can be called by any function that already has the error string ready. iwl_fw_dbg_collect_trig, on the other hand, does string formatting. The occurrences decrement is at iwl_fw_dbg_collect_trig, instead of iwl_fw_dbg_collect, which causes it to sometimes be skipped. Move it to the right location.
