Yuan Chen a7caec2a1b bpftool: Fix memory leak in dump_xx_nlmsg on realloc failure
[ Upstream commit 99fe8af069 ]

In function dump_xx_nlmsg(), when realloc() fails to allocate memory,
the original pointer to the buffer is overwritten with NULL. This causes
a memory leak because the previously allocated buffer becomes unreachable
without being freed.
