xfs: remove experimental tag for reverse mapping 



Reverse mapping has had a while to soak, so remove the experimental tag.
Now that we've landed space metadata cross-referencing in scrub, the
feature actually has a purpose.

Reject rmap filesystems with an rt device until the code to support it
is actually implemented.
