Subject: [PATCH] habanalabs: don't reset device when getting VRHOT

VRHOT event from the F/W indicates the device has reached a temperature of
100 Celsius degrees. In this case, the driver should only print this
information to the kernel log. The device will shutdown itself
automatically when reaching 125 degrees.
