wpa_supplicant: Complete radio works on disable event

While testing rfkill blocking of a scanning interface, it
was seen that the ongoing scan never completes. This happens
since EVENT_SCAN_RESULTS is discarded on a disabled interface.

Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.

To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
its own termination.
