USB: dwc3-msm: Fix issue related to error recovery for ERRATIC ERROR

If ERRATIC event irq is triggered by USB controller, it requires to perform
block reset USB controller as recovery mechanism as per SNPS data book.
Error recovery happens through allowing USB entering low power mode and
exit low power mode. We might see recovery failing as check for P3 state is
true as part of suspend and results in USB not entering low power mode.
Fix this issue by allowing USB enter low power mode in case of recovery
flag mdwc->in_restart set.
