net: Improve the warnings for dubious command line option combinations
Improve the warnings we give if the user specified a combination of -net
options which don't make much sense:
* Don't warn about anything if the config is the implicit default
"-net user -net nic" rather than one specified by the user (this will
only kick in for boards with no NIC or if CONFIG_SLIRP is not set)
* Diagnose the case where the user asked for NICs which the board
didn't instantiate (for example where the user asked for two NICs
but the board only supports one)

Its count of requested NICs is blissfully unaware of -device. In my
example, it comes up with nb_nics == 0 and seen_nics == 1.
