[PATCH] net: qed: make 'qed_ll2_ops_pass' as __maybe_unused

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

gcc warns about unused const variables even in header files when
building with W=1:

    In file included from include/linux/qed/qed_rdma_if.h:14,
                     from drivers/net/ethernet/qlogic/qed/qed_rdma.h:16,
                     from drivers/net/ethernet/qlogic/qed/qed_cxt.c:23:
    include/linux/qed/qed_ll2_if.h:270:33: error: 'qed_ll2_ops_pass' defined but not used [-Werror=unused-const-variable=]
      270 | static const struct qed_ll2_ops qed_ll2_ops_pass = {

This one is intentional, so mark it as __maybe_unused to it can be
included from a file that doesn't use this variable.
