Mikhail Lobanov 7e4385aa6d RDMA/cxgb4: Added NULL check for lookup_atid
[ Upstream commit e766e6a92410ca269161de059fff0843b8ddd65f ]

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.
