smbios_get_tables() bails out right away if leagacy mode is enabled
and won't generate any SMBIOS tables. At the same time x86 specific
fw_cfg_build_smbios() will genarate legacy tables and then proceed
to preparing temporary mem_array for useless call to
smbios_get_tables() and then discard it.

Drop legacy related check in smbios_get_tables() and return from
fw_cfg_build_smbios() early if legacy tables where built without
proceeding to non legacy part of the function.
