Adjust ENA driver to the new ena-com

Recent HAL change preparing to support ENAv2 required minor driver
modifications.

The ena_com_sq_empty_space() is not available in this ena-com, so it had
to be replaced with ena_com_free_desc().

Moreover, the ena_com_admin_init() is no longer using 3rd argument
indicating if the spin lock should be initialized, so it was removed.

Suppress excessive error prints in ENA TX hotpath

In FreeBSD, this is normal situation that the Tx ring is being full. In
hat case, the packet is put back into drbr and the next attempt to send
it is taken after the cleanup.

Too much logs like this can cause system instability and even cause the
device reset (because keep alive or cleanup could be missed).

To fix that, the log level of this message is changed to debug.

Upon this change upgrade the driver version to v0.8.2.

Update ena-com HAL to v1.1.4.3 and update driver accordingly

The newest ena-com HAL supports LLQv2 and introduces
API changes. In order not to break the driver compilation
it was updated/fixed in a following way:

* Change version of the driver to 0.8.0
* Provide reset cause when triggering reset of the device
* Reset device after attach fails
* In the reset task free management irq after calling ena_down. Admin
queue can still be used before ena_down is called, or when it is
being handled
* Do not reset device if ena_reset_task fails
* Move call of the ena_com_dev_reset to the ena_down() routine - it
should be called only if interface was up
* Use different function for checking empty space on the sq ring
(ena-com API change)
* Fix typo on ENA_TX_CLEANUP_THRESHOLD
* Change checking for EPERM with EOPNOTSUPP - change in the ena-com API
* Minor style fixes
