Subject: IB/multicast: Check ib_find_pkey() return value
From: Bart Van Assche <bart.vanassche@xxxxxxxxxxx>
commit d3a2418ee36a59bc02e9d454723f3175dcf4bfd9 upstream.
This patch avoids that Coverity complains about not checking the
ib_find_pkey() return value.
Fixes: commit 547af76521b3 ("IB/multicast: Report errors on multicast groups if P_key changes")
