accel/habanalabs: set hard reset flag if graceful reset is skipped

hl_device_cond_reset() might be called with the hard reset flag unset,
because a compute reset upon device release as part of a graceful reset
is valid.
If the conditions for graceful reset are not met, hl_device_reset() will
be called for an immediate reset. In this case a compute reset is not
valid, so it will be replaced with a hard reset together with a debug
message about it.
This message might be confusing, as it implies that a compute reset was
requested when it shouldn't. To prevent this confusion, set the hard
reset flag in hl_device_cond_reset() if going to an immediate reset.
