[PATCH 2/2] cobalt/trace: dovetail: remove TODO and return -ENOSYS for unportable features

[Hongzhan Chen via Xenomai]

Some of the features are unportable because ftrace does not
provide equivalent functionality to the ipipe tracer (namely double
buffering so that you can continue to record in flight-recorder mode
while a previous recording remains available).

We remove TODO to pass allyesconfig make.
