[dpdk-dev] [PATCH] ring: use direct cast to objtype fixes build error

[Ed Czeck <ed.czeck@atomicrules.com>]

build error:
include/rte_ring.h:459:22: error: invalid conversion from ‘void*’
to ‘void**’ [-fpermissive]
  ENQUEUE_PTRS(r, &r[1], prod_head, obj_table, n, void *);

Implicit casts of void* to void** are considered warnings in some
compilers.  E.g. g++ version 5.8.  Cast directly to object types
