efi_selftest: Do not check EFI_SIMPLE_NETWORK_RECEIVE_INTERRUPT

Do not check EFI_SIMPLE_NETWORK_RECEIVE_INTERRUPT in packet
receiving loop. This depends on the implementation and not
related to whether the packet can be received or not.

Whether the received packets are available or not is ensured
by wait_for_packet, and that is already done in the loop.
