staging: usbip: bugfix for deadlock

commit 438957f8d4a84daa7fa5be6978ad5897a2e9e5e5 upstream.

Interrupts must be disabled prior to calling usb_hcd_unlink_urb_from_ep.
If interrupts are not disabled, it can potentially lead to a deadlock.
The deadlock is readily reproduceable on a slower (ARM based) device
such as the TI Pandaboard.
