IB/core: Verify that QP is security enabled in create and destroy

commit 4a50881bbac309e6f0684816a180bc3c14e1485d upstream.

The XRC target QP create flow sets up qp_sec only if there is an IB link with
LSM security enabled. However, several other related uAPI entry points blindly
follow the qp_sec NULL pointer, resulting in a possible oops.

Check for NULL before using qp_sec.

Fixes: d291f1a65232 ("IB/core: Enforce PKey security on QPs")
