From: Leon Romanovsky <leonro@nvidia.com>

All QP creation flows called ib_create_qp_security(), but differently.
This caused to the need to provide exclusion conditions for the XRC_TGT,
because such QP already had selinux configuration call.

In order to fix it, move ib_create_qp_security() to the general QP
creation routine.
