commit e717f974ceedb8d045cf6c9ceed69289e545571c
bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e717f974ceedb8d045cf6c9ceed69289e545571c

--------------------------------

[ Upstream commit 7c6090ee ]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

If bpf_map_update_elem() failed, main() should return a negative error.
