[lttng-dev] [PATCH lttng-tools 01/10] Fix: bad file descriptors on close after rotation error

[Mathieu Desnoyers]

Ensure we don't try to close output stream file descriptors twice when a
trace file rotation error occurs (once at tracefile rotation, once when
closing the stream). Set the fd value to -1 after the first close to
ensure we don't try to close it again.
