[dm-devel] Patch to minimize noise with snapshots in emc_clariion checker

[Levy, Jerome]

Patch to stop emc_clariion_checker from logging messages when probes 
to snapshot LUNs occur. Notification is still available if logging is 
turned up (see condlog()) but normal probing of snapshots will no 
longer produce status messages. Path functionality on snapshot probes 
is unchanged.
