To modify the default connection method, a "btl_openib_connect <arg>"

should be passed via commandline.  However, there is a slight coding
bug in the openib connect code.  When registering the name of the
option, mca_base_param_reg_string will prepend the relevant info
("btl_openib_" in this case).  The existing code will require
"btl_openib_btl_openib_connect" instead of "btl_openib_connect".
This patch corrects this.
