net/bnxt: fix build

Fix build failures seen on Fedora Core 34 (GCC 11)
because of uninitialized variables.

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
 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

drivers/net/bnxt/tf_core/dpool.c:95:18: error:
‘index’ may be used uninitialized in this function
