bus: mhi: core: Fix check for syserr at power_up
commit 6403298c58d4858d93648f553abf0bcbd2dfaca2 upstream.
The check to see if we have reset the device after detecting syserr at
power_up is inverted. wait_for_event_timeout() returns 0 on failure,
and a positive value on success. The check is looking for non-zero
as a failure, which is likely to incorrectly cause a device init failure
if syserr was detected at power_up. Fix this.
Fixes: e18d4e9fa79b ("bus: mhi: core: Handle syserr during power_up")
