Use the helper virtio_find_vqs().
We add 'always', 'never', and 'inode' (default). '-o dax' continues to
operate the same which is equivalent to 'always'.
By the time this patch is applied, 'inode' mode is actually equal to
'always' mode, before the per-file DAX flag is introduced in the
following patch.

Fuse client can enable or disable per-file DAX inside guest by
chattr(1). Similarly the new state won't be updated until the file is
closed and reopened later.
It is worth nothing that it is a best-effort style, since whether
per-file DAX is enabled or not is controlled by fuse_attr.flags
Add one flag for fuse_attr.flags indicating if DAX shall be enabled for
this file.
When the per-file DAX flag changes for an *opened* file, the state of
the file won't be updated until this file is closed and reopened later.

This patchset adds support of per-file DAX for virtiofs, which is
inspired by Ira Weiny's work on ext4[1] and xfs[2].
There are three related scenarios:
1. Alloc inode: get per-file DAX flag from fuse_attr.flags. (patch 3)
2. Per-file DAX flag changes when the file has been opened. (patch 3)
