Re: [PATCH 1/2] tracing: fprobe: Remove unused local variable

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>

The 'ret' local variable in fprobe_remove_node_in_module() was used
for checking the error state in the loop, but commit dfe0d675df82
("tracing: fprobe: use rhltable for fprobe_ip_table") removed the loop.
So we don't need it anymore.

Fixes: dfe0d675df82 ("tracing: fprobe: use rhltable for fprobe_ip_table")
