usb: dwc3-msm: Relax PM wakelock if PM resume from B_SUSPEND state 



The driver holds PM wakelock if PM resume is called. If the
device was in B_SUSPEND(peripheral mode bus suspend) when
suspended earlier, then we will not be releasing the wakelock
from sm_work. Do so in order to allow system suspend to happen
again.
