[ Upstream commit c659b405b82ead335bee6eb33f9691bf718e21e8 ]
ip_dev_find() always returns real net_device address, whether traffic is
running on a vlan or real device, if traffic is over vlan, filling
endpoint struture with real ndev and an attempt to send a connect request
will results in RDMA_CM_EVENT_UNREACHABLE error. This patch fixes the
issue by using vlan_dev_real_dev().

The lookup_atid() function can return NULL if the ATID is
invalid or does not exist in the identifier table, which
could lead to dereferencing a null pointer without a
check in the `act_establish()` and `act_open_rpl()` functions.
Add a NULL check to prevent null pointer dereferencing.
