Howard Pritchard 8223d4cba0 btl/openib: disable XRC by default 
Change the default enable configure option XRC to disabled.  If a user want's
to give it a try they have to explicitly ask for it.

Modify the configury help message to indicate it is not enabled by default.

Related to #3890
Fixes #3969
