IB/isert: fix T10-pi check mask setting 

commit 0e12af84cd upstream.

A copy/paste bug (probably) caused setting of an app_tag check mask
in case where a ref_tag check was needed.

Fixes: 38a2d0d429 ("IB/isert: convert to the generic RDMA READ/WRITE API")
Fixes: 9e961ae73c ("IB/isert: Support T10-PI protected transactions")
