Duoming Zhou 8e537affc3 nfp: flower: handle acti_netdevs allocation failure
[ Upstream commit 84e95149bd341705f0eca6a7fcb955c548805002 ]

The kmalloc_array() in nfp_fl_lag_do_work() will return null, if
the physical memory has run out. As a result, if we dereference
the acti_netdevs, the null pointer dereference bugs will happen.

This patch adds a check to judge whether allocation failure occurs.
If it happens, the delayed work will be rescheduled and try again.

Fixes: bb9a8d031140 ("nfp: flower: monitor and offload LAG groups")
