Subject: [PATCH] DWC2: intializes the spin_lock earlier in the probe

The spinlock hsotg->lock is intialized at the end of the probe. However it
may be used from within dwc2_hcd_init(). This patch moves the
initialization before the call to dwc2_hcd_init(). This make the locking
correctness validator happy.
