Compiling a program including verbs.h with ICC fails with the following
error (seen with DPDK):
/root/development/rdma-core/build/include/infiniband/verbs.h(84):
warning #61: integer operation result is out of range
static void *__VERBS_ABI_IS_EXTENDED = ((uint8_t *) NULL) - 1;
Fixes: 6be16586e081 ("Infrastructure to support verbs extensions")
