[Qemu-stable] [PATCH] tap: properly initialize vhostfds

[Jason Wang]

Only tap->vhostfd were checked net_init_tap_one(), but tap->vhostfds were
forgot, this will lead qemu to ignore all fds passed by management through
vhostfds, and tries to create vhost_net device itself. Fix by adding this check
also.
