Jason Wang c87826a878 tap: fix NULL dereference when passing invalid parameters to tap
This patch forbid the following invalid parameters to tap:

1) fd and vhostfds were specified but vhostfd were not specified
2) vhostfds were specified but fds were not specified
3) fds and vhostfd were specified

For 1 and 2, net_init_tap_one() will still pass NULL as vhostfdname to
monitor_handle_fd_param(), which may crash the qemu.

Also remove the unnecessary has_fd check.
