[collectd] [PATCH] utils_mount.c: Fixed an unused variable warning on some systems.

[Sebastian Harl]

This warning appeared on systems using listmntent() or getv?fsstat() when
compiling with debugging disabled only. It was caused by the declaration of a
character array for use with sstrerror() inside a call to DEBUG().
