Remove unneeded symbol check for --list option.
This code actually checks whether the given symbol exists
in the kernel. But this is incorrect for online kernel/module
and offline module too.
- For online kernel/module, the kprobes itself already
ensured the symbol exist in the kernel.
- For offline module, this code can't access the offlined
modules. Ignore it.
