This is the first step toward moving MR invalidation decisions
to the core.  It will be needed by the upcoming RW API.

This makes sense even before the rdma rw stuff. We can
add this bit and get rid of the iser flagging (and when
nfs/srp will support remote invalidate they will use it too)

If someone else has a use for it ASAP feel free to send it along
with that.  The R/W code currently is my priority project because
the NVMe target driver will need it.  Once that and a few other
urgent items are off my plate I'll happily help out with various
cleanups on the client side MR API again.
