Johan Hovold 9f4bc5c304 usb: gadget: lpc32xx_udc: fix clock imbalance in error path 
commit 782be79e45 upstream.

A recent change fixing a device reference leak introduced a clock
imbalance by reusing an error path so that the clock may be disabled
before having been enabled.

Note that the clock framework allows for passing in NULL clocks so there
is no risk for a NULL pointer dereference.

Also drop the bogus I2C client NULL check added by the offending commit
as the pointer has already been verified to be non-NULL.
