dm thin: update stale "Status" Documentation

Browse Source 
Documentation/device-mapper-/thin-provisioning.txt's "Status" section no

That is, DM thinp is no longer "EXPERIMENTAL".  It has since seen
considerable improvement, has been fairly widely deployed and has
performed in a robust manner.

Update Documentation to dispel concern raised by potential DM thinp
users.
