virtio-9p-device: Avoid freeing uninitialized memory

In virtio_9p_device_init() there are 6x goto out that will lead to
v9fs_path_free() attempting to free unitialized path.data field.
Easiest way to trigger is: qemu-system-x86_64 -device virtio-9p-pci

Fix this by moving v9fs_path_init() before any goto out....

hw/9pfs: Fix segfault with 9p2000.u

When guest tries to chmod a block or char device file over 9pfs,
the qemu process segfaults. With 9p2000.u protocol we use wstat to
change mode bits and client don't send extension information for
chmod. We need to check for size field to check whether extension...

hw/9pfs: use O_NOFOLLOW for mapped readlink operation

With mapped security models like mapped-xattr and mapped-file, we save the
symlink target as file contents. Now if we ever expose a normal directory
with mapped security model and find real symlinks in export path, never...
