[Pacemaker] [PATCH 9/8 ] errata, only close file descriptors if that had been opened

[Bernd Schubert]

cl_log: Only close file descriptors if that had been opened

This patch also could be merged with the 6th patch in the series
(restore old open/write/close semantics). It fixes a valgrind
warning about invalid close().
