Fix pci_add nic not to exit on bad model
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to
create the NIC. When MODEL is unknown or "?", this prints to stderr
and terminates the program.
Change pci_nic_init() not to treat "?" specially, and to return NULL
on failure. Switch uses during startup to new convenience wrapper
pci_nic_init_nofail(), which behaves just like pci_nic_init() used to
do.
Bonus bug fix: we now check for qdev_init() failing there.
