arch/x86/smbios: Consider corner case of Part Number
In case of all DMI Type 17 to be empty, the strip trailing whitespace
code will have a zero length Part Number entry, which will cause
exception when using (len - 1) where len is zero. Add extra code to
cover this corner case.
BUG=b:76452395
TEST=Boot up fine with meowth platform, without this patch system will
get stuck at "Create SMBIOS type 17".
