[PATCH 1/5] md/raid1,raid10: drop unused mddev arg from check_decay_read_errors()

[Hiroshi Nishida <nishidafmly@gmail.com>]

check_decay_read_errors() only ever touches the passed rdev; the mddev
parameter has been unused. Remove it and update the sole caller in
exceed_read_errors().

No functional change.
