[PATCH v2 3/4] trace-cmd: Create ftrace instances before using them.

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

Ftrace instances should be created physically in the tracefs, before
trying to access its files. In record_trace() function, the call to
make_instances() should be before the logic which reads the instance's
tracing file.
