The FreeBSD nvme driver has reset the nvme controller twice on attach to address a theoretical issue assuring the hardware is in a known state. However, exierence has shown the second reset is unnecessary and increases the time to boot. Eliminate the second reset. Should there be a situation when you need a second reset (for buggy or at least somewhat out of the mainstream hardware), the hardware option NVME_2X_RESET will restore the old behavior. Document this in nvme(4). If there's any trouble at all with this, I'll add a sysctl tunable to control it.
