Revert "iwlwifi: do not perferm force reset while doing scan"

This reverts commit 7acc7c683a747689aaaaad4fce1683fc3f85e552. It was
applied to avoid possible warning in ieee80211_restart_hw, however
reason of the warning were races in mac80211, currently hopefully fixed.

Not reseting device when performing scan is bad for two reasons.

When forcing reset from iwl_check_stuck_queue(), in case of fail,
reset will be repeated until scan finish. But since firmware is in bad
shape, scan only finish after scan_check work (about 7s). So we will
delay the reset, what is not good behaviour.

When forcing reset from iwl_recover_from_statistics(), we will not
repeat the reset, so we will not perform reset at all when needed.
