nvethernet: Restrict > 9K jumbo only in eqos

Browse Source 
Issue: MGBE supports upto 16K jumbo size.
       There is enough MTL queue space also
       for 16K packet even with all 10 queues
       enabled in MGBE. So no need to restrict
       > 9k jumbo to single channel config only.
FIx:   For MGBE, unconditionally allow upto 16K
       jumbo size setting.
