habanalabs: avoid unnecessary error print
When sending a packet to FW right after it made reset, we will get
packet timeout. Since it is expected behavior, we don't need to
print an error in such case.
Hence, when driver is in hard reset it will avoid from printing error
messages about packet timeout.
