dwc3-msm: Block doorbell to GSI from USB wrapper

It is required to block doorbell to GSI to avoid USB wrapper
from ringing doorbell before queuing stop xfer command to GSI
endpoint as part of stopping controller. Otherwise USB wrapper
is accessing IPA doorbell register while clocks are off after
restarting USB controller. Hence fix it by blocking doorbell
to GSI for avoiding this issue before queueing endxfer command
to GSI endpoint.
