[PATCH v6 01/14] usb: chipidea: remove unneeded NULL check

From: Alexander Shishkin <alexander.shishkin@linux.intel.com>

As reported by Dan Carpenter, there is a NULL check in udc_start() that
follows a dereference of the pointer that's being checked. However, at
that point udc pointer shouldn't ever be NULL and if it is, the dereference
should cause an oops.
