virtio: fix coverity warnings
Fix 3 coverity warnings
1. api_format.c: init net_ns = 0 and remove its corresponding vec_add and
vec_free
2. netlink.c (reported in tap.c before the code was removed): resource leaked
due to fd is not close
3. tap.c: subtract 1 for size when calling strncpy to accommodate the
terminated NULL character
