cxgb4 : Fix missing initialization of win0_lock

[ Upstream commit e327c225c911529898ec300cb96d2088893de3df ]

win0_lock was being used un-initialized, resulting in warning traces
being seen when lock debugging is enabled (and just wrong)

Fixes : fc5ab0209650 ('cxgb4: Replaced the backdoor mechanism to access the HW
 memory with PCIe Window method')
