btrfs-progs: show meaningful msgs for replace cmd upon raid56
This depends on the kernel patch:
[PATCH] btrfs:replace EINVAL with EOPNOTSUPP for dev_replace
This catches the EOPNOTSUPP and output msg that says dev_replace raid56
is not currently supported. Note that the msg will only be shown when
run dev_replace not in background.
