Today if multiple FDs are sent from the VMM to the backend in a VHOST_USER_ADD_MEM_REG message, one FD will be mapped and the remaining FDs will be leaked. Therefore if multiple FDs are sent we report an error and fail the operation, closing all FDs in the message. Likewise in case the VMM sends a message with a size less than that of a memory region descriptor, we add a check to gracefully report an error and fail the operation rather than crashing.
