Subject: [PATCH] net: marvell: prestera: fix a couple NULL vs IS_ERR() checks
The __prestera_nexthop_group_create() function returns NULL on error
and the prestera_nexthop_group_get() returns error pointers. Fix these
two checks.
Fixes: 0a23ae237171 ("net: marvell: prestera: Add router nexthops ABI")
