Subject: [PATCH 4.8 27/92] usb: dwc3: Fix error handling for core init

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vivek Gautam <vivek.gautam@...eaurora.org>

commit 9b9d7cdd0a20a8c26a022604580f93516ad69c36 upstream.

Fixing the sequence of events in dwc3_core_init() error exit path.
dwc3_core_exit() call is also removed from the error path since,
whatever it's doing is already done.

Fixes: c499ff7 usb: dwc3: core: re-factor init and exit paths
