tracing: Remove unused variable in tracing_trace_options_show()

The flags and opts used in tracing_trace_options_show() now come directly
from the trace array "current_trace_flags" and not the current_trace. The
variable "trace" was still being assigned to tr->current_trace but never
used. This caused a warning in clang.
