[PATCH md 006 of 10] Only try to print recovery/resync status for personalities that support recovery

[NeilBrown <neilb@suse.de>]

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.
