[PATCH] md: only try to print recovery/resync status for personalities that support...

The introduction of 'resync=PENDING' (for read-only devices) caused that
message to appear for non-syncable arrays like raid0 and linear.  Simplest
thing is to not try to print any resync info unless the personality clearly
supports it.
