[dmidecode] dmidecode should omit warning about SMBIOS version when -q is set

[Jens Rosenboom]

As in particular scripts call dmidecode often with -s (implying -q) and
expect to get only a single word (and in particular only a single line
of output), I propose that in this case the warning about an unsupported
SMBIOS version should be ommited. Most scripts won't be able to handle
the warning properly anyway, also most -s options should still continue
to work. My patch would look like this:
