LU-12931 general: fix some cfs_time_seconds() inconsistencies.

LU-12931 general: fix some cfs_time_seconds() inconsistencies.

mgc_process_log:
  the value stored in 'secs' has units of 'jiffes' which is
  confusing.  So change the name to 'timeout'.
ptl_recover_import:
  the value stored in 'secs' has units of 'jffied' which is
  confusing.  It is reported in a CDEBUG message as 'seconds'.
  So rename to 'timeout' and report 'obd_timeout', which is in
  seconds.
