md-cluster/raid10: don't call remove_and_add_spares during reshaping stage 

remove_and_add_spares is not needed if reshape is
happening in another node, because raid10_add_disk
called inside raid10_start_reshape would handle the
role changes of disk. Plus, remove_and_add_spares
can't deal with the role change due to reshape.
