A handful of fixes:
* missing RCU grace period enforcement led to drivers freeing
data structures before; fix from Dedy Lansky.
* hwsim module init error paths were messed up; fixed it myself
after a report from Colin King (who had sent a partial patch)
* kernel-doc tag errors; fix from Luca Coelho
* initialize the on-stack sinfo data structure when getting
station information; fix from Sven Eckelmann
* TXQ state dumping is now done from init, and when TXQs aren't
initialized yet at that point, bad things happen, move the
initialization; fix from Toke Høiland-Jørgensen.
