Subject: [PATCH v2 1/2] ftrace: Rename set_tracer_flags()'s local variable
 trace_flags

set_tracer_flags() have a local variable named trace_flags which have
same name with global one.
Actually, using tracer_flags should be better by its meaning.

Changelog:
v1->v2: Simplied another patch in this patchset, no change in this patch.

[ Impact: cleanup ]
