cmd: bound the PVID and say something when it is refused

Browse Source 
"pvid 1 5000" packed 5000 into the 12-bit PVID field and truncated on the
way, so the port ended up with a PVID nobody chose. 0 and anything above
4094 are refused now, matching what the VLAN table can hold. A failed
parse used to be dropped without a word; both cases print the usage line.
