[PATCH net-next 03/11] net: constify dev pointer in misc instance lock helpers

[Jakub Kicinski <kuba@kernel.org>]

lockdep asserts and predicates can operate on const pointers.
In the future this will let us add asserts in functions
which operate on const pointers like dev_get_min_mp_channel_count().
