qemu-doc: The "-net nic" option can be used with "netdev=...", too

Browse Source 
Looks like we missed to document that it is also possible to specify
a netdev with "-net nic" - which is very useful if you want to
configure your on-board NIC to use a backend that has been specified
with "-netdev".

Configure or create an on-board (or machine default) Network Interface Card
(NIC) and connect it either to VLAN @var{n} (@var{n} = 0 is the default), or
to the netdev @var{nd}. The NIC is an e1000 by default on the PC
target. Optionally, the MAC address can be changed to @var{mac}, the
device address set to @var{addr} (PCI cards only),
and a @var{name} can be assigned for use in monitor commands.
