vmm: ignore and warn TAP FDs send in vm.create

Browse Source 
This does the same thing as df2a7c17 ("vmm: Ignore and warn TAP FDs
sent via the HTTP request body"), but for the vm.create endpoint,
which also previously would accept file descriptors in the body, and
try to use whatever fd occupied that number as a TAP device.
