[PATCH v1 1/1] net/ice: fix NULL pointer dereference in DCF

When calling into common parameter checks and subsequent action check
callbacks, the DCF path never supplied the `driver_ctx` struct, yet the
callback itself dereferenced the struct.

Fix it by supplying the DCF adapter struct as context.
