Recent changes to count number of matching symbols when creating a kprobe event failed to take into account kernel modules. As such, it breaks kprobes on kernel module symbols, by assuming there is no match.
Fix this my calling module_kallsyms_on_each_symbol() in addition to kallsyms_on_each_match_symbol() to perform a proper counting.

I noticed this patch was added and then dropped in the 6.1 stable queue. Is there any issue with it? I'll fix it ASAP.
It broke the build.
