USB: dwc3-msm: Perform DBM config/unconfig under spinlock protection
There is a possibility of dwc3_msm_ep_queue() and msm_ep_unconfig() racing
each other if suspend happens right after configured. This scenario will
result in NOC error if start_xfer command gets queued after
msm_ep_unconfig(). Hence fix the issue by adding spinlock protection for
DBM endpoint configuration and unconfiguration.
