[XFS] add a FMODE flag to make XFS invisible I/O less hacky
XFS has a mode called invisble I/O that doesn't update any of the
timestamps. It's used for HSM-style applications and exposed through
the nasty open by handle ioctl.
Instead of doing directly assignment of file operations that set an
internal flag for it add a new FMODE_NOCMTIME flag that we can check
in the normal file operations.
(addition of the generic VFS flag has been ACKed by Al as an interims
solution)
