sfxge(4): cleanup: make VPD lookups quieter

A lookup on a VPD entry which is missing reports several failure
messages as it propagates through wrapper functions. Restructured
the wrappers to treat this gracefully as an expected case.

sfxge: fix common code VPD iterator and duplicate tag verification

Fix efx_vpd_hunk_next() which has -- since its inception -- failed to
correctly iterate over the tags and keywords contained in the VPD data.
Only the first tag or keyword would be returned and the next call with
*contp == 1 would walk to the end of the data and finish.

This was spotted when fixing up errors spotted by Prefast code analysis
(which neglected to set all of the out parameters in all successful cases)

Also fix efx_vpd_verify() on Siena and EF10 which (as a side effect of
correctly iterating over all the tags and keywords) was failing as it
detected that both the static VPD and dynamic VPD storage contained an
RV keyword in the VPD-R tag. This is intentional as the static VPD and
dynamic VPD are stored separately (firmware merges their contents and
computes a new RV keyword checksum for the data readable from the VPD
capability in PCIe configuration space).

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.

sfxge: cleanup: report error on failure path in efx_vpd_hunk_verify

If the VPD is corrupt and contains an 'RV' keyword before the
END tag, then this function could return without setting the
return code to report the error.

Found by prefast.
