If we are associated and scanning is performed , sw_scan_complete callback
is done after we get back to operating channel, so we do not perform
phy calibration and queue cal work. Fix this by run calibration from
sw_scan_complete().
Fixes: bbd10586f0df ("mt76x0: phy: do not run calibration during channel
switch")
