mac80211: fix remain-on-channel cancellation

Browse source 
Ilan's previous commit 1b894521e6 ("mac80211: handle HW
ROC expired properly") neglected to take into account that
hw_begun was now always set in the software implementation
as well as the offloaded case.

Fix hw_begun to only apply to the offloaded case to make
the check in Ilan's commit safe and correct.
