arch/x86/smbios: fix length calculation for SMBIOS type 17

Browse source 
Different DIMM modules give different SMBIOS type 17 lengths, so we
can't use `meminfo->dimm_cnt*len' for entry struct size, otherwise
it'll give a wrong SMBIOS size when two or more different DIMMs are
installed on the machine.
