9p: fix kernel-doc warning for enum p9_session_flags

kernel-doc cannot parse enum p9_session_flags, since its documentation
comment is followed by #define lines instead of the enum declaration:

  fs/9p/v9fs.h:31 : error: Cannot parse enum!

Move the three #define lines below the enum whose values they are
derived from, and give V9FS_ACCESS_ANY and V9FS_ACCESS_MASK their own
kernel-doc comments with the descriptions they had in the enum comment.

Also document the four enum members that had no description, using the
corresponding mount option wording from
Documentation/filesystems/9p.rst.
