hw/misc/ivshmem: Fix ivshmem_recv_msg() to also work on big endian systems
The "slow" ivshmem-tests currently fail when they are running on a
big endian host:
$ uname -m
ppc64
$ V=1 QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 tests/ivshmem-test -m slow
/x86_64/ivshmem/single: OK
/x86_64/ivshmem/hotplug: OK
/x86_64/ivshmem/memdev: OK
/x86_64/ivshmem/pair: OK
/x86_64/ivshmem/server-msi: qemu-system-x86_64:
-device ivshmem-doorbell,chardev=chr0,vectors=2: server sent invalid ID message
Broken pipe
The problem is that the server side code in ivshmem_server_send_one_msg()
correctly translates all messages IDs into little endian 64-bit values,
but the client side code in the ivshmem_recv_msg() function does not swap
the byte order back. Fix it by passing the value through le64_to_cpu().
