net/mlx5: E-Switch, Initialize eswitch acls ns when eswitch is enabled
Currently eswitch flow steering (FS) namespace of vport's ingress and
egress ACL are enabled when FS layer is initialized. This is done even
when eswitch is diabled. This demands that total eswitch ports to be
known to FS layer without eswitch in use.
Given the FS core is not dependent on eswitch, make namespace init and
cleanup routines as helper routines to be invoked only when eswitch is
needed.
With this change, ingress and egress ACL namespaces are created only
when eswitch legacy/offloads mode is enabled.
