Better error messages for broken reshape
mdadm --grow --continue has no functionality to restore critical sectors
if reshape was stopped during operation. This functionality belongs to
assemble or incremental.
This patch adds hints to error messages, to try to reassemble array in
case of reshape failure to restore critical sector, so assemble can
handle restoration.
