mempool/octeontx2: fix build with icc

The Intel compiler is pickier about casts and generates:
otx2_mempool_ops.c(344):
     error #191: type qualifier is meaningless on cast type
  	int64_t * const addr = (int64_t * const)
  	                        ^
This is because of the nature of const.
In this example, the expression is being cast into a pointer
that can not be modified. This is meaningless because the
expression is already a lvalue.
