rt2x00: Don't frequently reset beacon interval in AdHoc mode
Commit 0204464329c17ba6d293e1899f71223599a0e582 "Check for specific changed flags when updating the erp config" changed the way in which a new beacon interval gets handled. However, due to a bug in rt2800usb and rt2800pci the beacon interval was reset during each scan, thus causing problems in AdHoc mode. Fix this by not cleaning up the beacon interval when killing the beacon queue but just prevent the device from sending out beacons.
