qcacmn: Fix interrupt handling after pdev deinit

Browse Source 
The interrupt polling timer needs to be disabled when the host
device driver decides to unload. Not handling this would cause
in processing of pending interrupts and access data structures
that are being deinitialized causing system instability.
