Fix CVE-2021-3416
Some NIC supports loopback mode and this is done by calling
nc->info->receive() directly which in fact suppresses the effort of
reentrancy check that is done in qemu_net_queue_send().
Unfortunately we can use qemu_net_queue_send() here since for loop
back there's no sender as peer, so this patch introduce a
qemu_receive_packet() which is used for implementing loopback mode
for a NIC with this check.
NIC that supports loopback mode will be converted to this helper.

Fix CVE-2021-3392
While processing SCSI i/o requests in mptsas_process_scsi_io_request(),
the Megaraid emulator appends new MPTSASRequest object 'req' to
the 's->pending' queue. In case of an error, this same object gets
dequeued in mptsas_free_request() only if SCSIRequest object
'req->sreq' is initialised. This may lead to a use-after-free issue.
Unconditionally dequeue 'req' object from 's->pending' to avoid it.

In arm, the default value of CONFIG_KVM is no.
While the target is arm, the compilation fails because
the function "kvm_arm_cpu_feature_supporte" is declared
or the function "kvm_arm_get_one_reg" is not defined.
