[lvm-devel] [PATCH 25/29] Check for unlink result

[Zdenek Kabelac]

Even if we intentionally wish to silently ignore any error from
unlink in this place - it might be still good idea to put at least
a debug message to get the reason for failure.

Test makes static analyzer happier about checked unlink result.
