[ Upstream commit 5612ea8b55 ]

This fixes the build with -Werror -Wall.

btf_dumper.c:71:31: error: variable 'finfo' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
   71 |         info.func_info = ptr_to_u64(&finfo);
      |                                      ^~~~~

prog.c:2294:31: error: variable 'func_info' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
 2294 |         info.func_info = ptr_to_u64(&func_info);
      |

v2:
  - Initialize instead of using memset.
