lib: Fix overwriting action after deactivating callback

Browse source 
If one of the callbacks called from fpi_imgdev_deactivate_complete()
was reactivating the device, then we would be overwriting whichever
"action" got set in the callback, leading to
fpi_imgdev_activate_complete() failing as it doesn't handle the "none"
action.

Reset the action before calling the callbacks.
