Dynamic memory mode allowes zero socket-mem because all the
required memory could be allocated on demand.

Now that i think of it, maybe it's not that simple.
--socket-mem/-m flag with zero is still an invalid value *if*
--legacy-mem is involved. However, it is a valid value in non-legacy mode.
So maybe the test should reflect this, and the previous fix should have
instead added a check for legacy mode rather than disabling the zero
check outright.

I don't think that it's a big deal, because "--socket-mem=0 --legacy-mem"
quickly fails with clear:
EAL: WARNING: Master core has no memory on local socket!
IMHO, It's actually more informative than previous:
EAL: invalid parameters for --socket-limit
I agree that we could add a test for a legacy-mem cases, but that's a bit
different task.
