net: dsa: qca8k: fix mdb add/del case with 0 VID

Browse Source 
commit dfd739f182b00b02bd7470ed94d112684cc04fa2 upstream.

The qca8k switch doesn't support using 0 as VID and require a default
VID to be always set. MDB add/del function doesn't currently handle
this and are currently setting the default VID.

Fix this by correctly handling this corner case and internally use the
default VID for VID 0 case.
