[PATCH 02/35] fs-tests: integck: check deletion errors in rm_minus_rf_dir

[Artem Bityutskiy]

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

Modify the 'rm_minus_rf_dir()' function to return -1 in case of any
errors during deletions. Make 'integck()' handle the errors. Also
introduce a 'pcv()' function to print error message if -v command
line option was specified.
