usb: gadget: gsi: Decrement USB gadget pm usage count on cable disconnect 



Currently USB GSI function driver increments USB gadget device's
pm usage count on set_alt() and decrements on USB bus suspend or
USB cable disconnect case. Current code is not decrementing this
usage count when sm_state is STATE_INITIALIZED and USB cable is
disconnected (i.e. event EVT_DISCONNECTED posted). Fix this issue
by decrementing USB gadget device's pm usage count by addding check
for event EVT_DISCONNECTED when sm_state is STATE_INITIALIZED.
