[ Upstream commit 4ca501d6aaf21de31541deac35128bbea8427aa6 ]

Clang warns:

../drivers/infiniband/core/security.c:351:41: warning: converting the
enum constant to a boolean [-Wint-in-bool-context]
        if (!(qp_attr_mask & (IB_QP_PKEY_INDEX || IB_QP_PORT)) && qp_pps) {
                                               ^
1 warning generated.

A bitwise OR should have been used instead.
