dm mpath: cleanup reinstate_path() et al based on code review
fail_path() will print a "Failing path ..." message but reinstate_path() doesn't print a "Reinstating path ...". Add that message to reinstate_path() to add symmetry and aid system debugging. Remove reinstate_path()'s check for the path_selector providing .reinstate_path hook. All path selectors provide this and any future ones must too. activate_path() calls pg_init_done() with SCSI_DH_DEV_OFFLINED but pg_init_done() doesn't expicitly handle it in its swicth statement. Add SCSI_DH_DEV_OFFLINED to the default case. Signed-off-by: Mike Snitzer <snitzer@redhat.com>
