sfxge(4): fix diagnostics support build without Siena

The compilation failed because __efx_sram_pattern_fns was used in
efx_nic.c, but defined in efx_sram.c which is only needed when
supporting Siena.

To fix it move all the code using __efx_sram_pattern_fns into
Siena-specific files (except for the definition in efx_sram.c itself,
as that file only needs to be included in Siena-supporting builds
anyway).

The functions to test registers and tables are unlikely to apply to any
new hardware and so can be moved into Siena files. Since Huntington
such tests have been implemented in firmware.

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: 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.
