ixgbe: update all DESC_ADV macros to accept a ring pointer

Browse Source 
All of the DESC_ADV macros are currently needing the pointers to be
de-referenced before accessing the ring.  Instead of having to add all of
the asterisks it is easier to just update the macro to expect a pointer to
the ring.
