greybus: es2: disable cport-in after remove greybus host device

Browse Source 
This allows greybus to do operations before being removed.

Tested by removing the gb-es2.ko module on both EVT1.5 and qemu with
gbsim. The driver removes the greybus host device successfully before
disabling the urbs. The errors are still coming ("urb cport in error -2
(dropped)"), but with an error value -2 (ENOENT) instead of -108. And
that happens while the urbs are disabled, not while doing greybus
operations.
