[dpdk-dev] [PATCH v2] net/bnxt: fix build failure

[Ajit Khaparde]

Fix build failures because of uninitialized variables.

../drivers/net/bnxt/tf_ulp/ulp_mapper.c: In function ‘ulp_mapper_index_tbl_process’:
../drivers/net/bnxt/tf_ulp/ulp_mapper.c:2252:43: error: ‘*(unsigned int *)((char *)&glb_res + offsetof(struct bnxt_ulp_glb_resource_info, resource_func))’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
 2252 |         struct bnxt_ulp_glb_resource_info glb_res;
      |                                           ^~~~~~~
../drivers/net/bnxt/tf_ulp/ulp_mapper.c:2252:43: error: ‘glb_res.resource_type’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

../drivers/net/bnxt/tf_core/dpool.c: In function ‘dpool_defrag’:
../drivers/net/bnxt/tf_core/dpool.c:95:18: error: ‘index’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
   95 |         uint32_t index;
      |                  ^~~~~
