[PATCH net-next v3 6/6] devlink: add missing NULL checks for devlink ops

[Jakub Kicinski]

Commit 76726ccb7f46 ("devlink: add flash update command") and
commit 2d8dc5bbf4e7 ("devlink: Add support for reload")
access devlink ops without NULL-checking. Add the missing checks.
Note that all drivers currently implementing devlink pass non-NULL
ops, so this is not a problem.
