usb: dwc3: Prevent continuous retries on error event

Upon USB core generating an erratic error event, the
dwc3-msm driver resets and restarts the core. Even
after this if core could not recover, the driver
keep on trying the same in a infinite loop. This could
lead to the hogging of system resources leading to
system failure. Prevent this by trying a maximum of three
times to recover upon erratic error event.

An example of continuous generation of error events is
a DCP charger detected as SDP by the PMIC and core entering
device mode. In this case, the core could not recover
even after several tries.
