net: Fix VM start with '-net none'
Commit 50e32ea8f31035877decc10f1075aa0e619e09cb changed the behaviour
for the return type of net_client_init() when a nic type with no init
method was specified. 'none' is one such nic type. Instead of returning
0, which gets interpreted as an index into the nd_table[] array, we
switched to returning -1, which signifies an error as well.
That broke VM start with '-net none'. Testing was only done with the
monitor command 'pci_add', which doesn't fail.
The correct fix would still be to return 0+ values from
net_client_init() only when the return value can be used as an index to
refer to an entry in nd_table[]. With the current code, callers can
erroneously poke into nd_table[0] when -net nic is used, which can lead
to badness.
However, this commit just returns to the previous behaviour before the
offending commit.
