Subject: [PATCH v2 19/25] staging: lustre: libcfs: update debug messages

From: Dmitry Eremin <dmitry.eremin@...el.com>

For cfs_cpt_bind() change the CERROR to CDEBUG. Make the debug
message in cfs_cpt_table_create_pattern() more understandable.
Report rc value for when cfs_cpt_create_table() fails.
