Subject[PATCH 3/6] selftests/ftrace: Have reset_ftrace_filter handle modules
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

If a function probe in set_ftrace_filter belongs to a module, it will
contain the module name. Like:

wmi_query_block [wmi]:traceoff:unlimited

But writing:

'!wmi_query_block [wmi]:traceoff' > set_ftrace_filter

will cause an error. We still need to write:

'!wmi_query_block:traceoff' > set_ftrace_filter
