smbios-mdr: Clean up warnings from newer compiler

No functional change. Cleaned up appropriate code to work around
compiler warnings. The switch to Meson also entails a newer compiler
version, which gives more warnings than before.

Due to the trivial nature of this change, it was requested that it be
merged into a previous patch instead of creating a new patch.

Tested: It builds and it runs, as expected.

 Updating the gRPC handler, and surrounding code, to make use of the
 smbios_file module just added. The actual gRPC call remains unchanged.
