nl80211: do not block when driver aborts scan

Drivers may abort a scan by calling cfg80211_scan_done() with a struct
cfg80211_scan_info that sets aborted to true.

To avoid blocking forever consider both NL80211_CMD_NEW_SCAN_RESULTS
and NL80211_CMD_SCAN_ABORTED when waiting for scan results.

Tested with Broadcom's bcmdhd driver.
