Yafang Shao 780f072f4f bpf: Clear the probe_addr for uprobe ...

[ Upstream commit 5125e757e6 ]

To avoid returning uninitialized or random values when querying the file
descriptor (fd) and accessing probe_addr, it is necessary to clear the
variable prior to its use.

Fixes: 41bdc4b40e ("bpf: introduce bpf subcommand BPF_TASK_FD_QUERY")
