Subject: net/mlx5: FPGA and IPSec initialization to be before flow steering
Patch-mainline: v4.17-rc1
Git-commit: 04e87170b0964d22c67245b739f56c3fe12fda54
References: bsc#1103990 FATE#326006

Some flow steering namespace initialization (i.e. egress namespace)
might depend on FPGA capabilities. Changing the initialization order
such that the FPGA will be initialized before flow steering.

Flow steering fs cmds initialization might depend on
IPSec capabilities. Changing the initialization order such
that the IPSec will be initialized before flow steering as well.
