tracing/kprobes: Fix symbol counting logic by looking at modules as well
commit 926fe783c8a64b33997fec405cf1af3e61aed441 upstream.
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.
