i40e: Fix i40e_debug() to use struct i40e_hw argument

i40e_debug() macro takes struct i40e_hw *h as first argument. But the
macro body uses hw instead of h. This has been working so far because hw
happens to be the name of the variable in the context where the macro is
expanded. Fix the macro to use the passed argument.
