smbios: Clean up error handling in smbios_add()
Calling error_report() in a function that takes an Error ** argument
is suspicious. smbios_entry_add() does that, and then exit()s. It
also passes &error_fatal to qemu_opts_validate(). Both wrong, but
currently harmless, as its only caller passes &error_fatal. Messed up
in commit 1007a37e20
. Clean it up.
