[PATCH 22/35] fs-tests: integck: teach dir_remove return error and fix a memory leak

[Artem Bityutskiy]

From: Artem Bityutskiy <Artem.Bityutskiy at nokia.com>

Teach 'dir_remove()' to return an error to the caller if it fails to
remove the directory. Also, there was a memory leak - the 'path'
string was not freed - fix it as well.
