USB: dwc3_msm: Disable all events before error recovery for Erratic event

Currently as part of Erratic event handling, dumping all relevant registers
and then scheduling work for block reset. This does lead to erratic event
getting fired continuously and might result in watchdog crash. Hence
disable all events in DEVTEN regiser before doing block reset and reenable
the events once block reset is completed.
