RDMA/cxgb4: Fix potential null-ptr-deref in pass_establish()
[ Upstream commit 283861a4c52c1ea4df3dd1b6fc75a50796ce3524 ]
If get_ep_from_tid() fails to lookup non-NULL value for ep, ep is
dereferenced later regardless of whether it is empty.
This patch adds a simple sanity check to fix the issue.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 944661dd97f4 ("RDMA/iw_cxgb4: atomically lookup ep and get a reference")
