USB: dwc3-msm: Disable DBM endpoint in msm_ep_unconfig if no req queued
There is a chance that error might occur in connect_work before
endless request is queued to USB controller and bails out. In this case,
DBM endpoint will not be disabled and results in setendpoint config
command timeouts after next connect and could cause usb endpoint enable
fails. Fix this by disabling DBM endpoint corresponding to USB endpoint
in msm_ep_unconfig() if there are no requests queued to USB endpoint.
