net: qede: Initialize qede_ll_ops with designated initializer

After a recent change [1] in clang's randstruct implementation to
randomize structures that only contain function pointers, there is an
error because qede_ll_ops get randomized but does not use a designated
initializer for the first member:

  drivers/net/ethernet/qlogic/qede/qede_main.c:206:2: error: a randomized struct can only be initialized with a designated initializer
    206 |         {
        |         ^

Explicitly initialize the common member using a designated initializer
to fix the build.
