powerpc/powernv: copy/paste - Mask SO bit in CR

2018-06-04T12:58:41Z

NX can set the 3rd bit in CR register for XER[SO] (Summary overflow) which is not related to paste request. The current paste function returns failure for a successful request when this bit is set. So mask this bit and check the proper return status.
