sfxge(4): remove Falcon-specific concurrency check

Falcon support has been withdrawn from libefx, however, there is still
an obsolete Falcon-specific assertion that efx_mac_stats_upload()
and efx_port_poll() aren't concurrent. To be consistent with an overall
Falcon support revocation it's desirable to remove it.

Fix debug build invalid assertion failure.

sfxge(4): make MAC naming consistent with other modules

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

sfxge(4): query and use current MTU if setting the MTU fails

This allows the driver to fall back to the largest usable MTU if a
user attempts to configure an unprivileged function with an MTU higher
than that of the attached port.

sfxge: if supported by firmware, use enhanced SET_MAC command to only configure the MTU

This allows an MTU change to be requested on unpriviliged functions
without also setting all the other parameters supported by MC_CMD_SET_MAC.

The enhanced SET_MAC command was introduced in v4_7 firmware.

sfxge: add prefast annotation to common code return types

Using a typedef for common code return types (rather than "int")
allows the Prefast static analyser to understand when a function
has been successful (and thus when its postconditions must hold).

This greatly reduces then number of false positives reported by
prefast for error paths in common code functions.
