ath5k: fix suspend-related oops on rmmod
Based on a patch by Elias Oltmanns, we call ath5k_init in resume even if we didn't previously open the device. Besides starting up the device unnecessarily, this also causes an oops on rmmod because mac80211 will not invoke ath5k_stop and softirqs are left running after the module has been unloaded. Add a new state bit, ATH_STAT_STARTED, to indicate that we have been started up.
