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.
