usb: increase ohci watchdog delay to 275 msec
commit ed6d6f8f42d7302f6f9b6245f34927ec20d26c12 upstream.
Increase ohci watchout delay to 275 ms. Previous delay was 250 ms
with 20 ms of slack, after removing slack time some ohci controllers don't
respond in time. Logs from systems with controllers that have the
issue would show "HcDoneHead not written back; disabled"
