Pierre Pronchery c4ec2918f2 bhyve: avoid buffer overflow in pci_vtcon_control_send 
The program copies an input buffer to an output buffer without verifying
that the size of the input buffer is less than the size of the output
buffer, leading to a buffer overflow.

Inside the function pci_vtcon_control_send, the length of the iov buffer
is not validated before copy of the payload.

(cherry picked from commit 8934002959)

This is a follow-up to the fix for HYP-19, addressing another condition
where an overflow might still occur. (Spotted by jhb@, thanks!)
