gsm: finish all disable commands before returning

Browse Source 
Rearrange the primary and secondary-port disable operations so that
there's a linear chain of callbacks rather than a second dangling
callback chain for the secondary port; it's possible for the primary
port operations to complete, and for the callback to finish and start
tearing down the entire device, before the secondary port commands
run.
