[v2,05/20] smbios: get rid of smbios_smp_sockets global

Commit Message

it makes smbios_validate_table() independent from
smbios_smp_sockets global, which in turn lets
smbios_get_tables() avoid using not related legacy code.

goal here is to isolate legacy handling from generic smbios_get_tables()
