erase/write: Deselect all smaller blocks when large block is selected

Previously the logic which selected large block did deselect of
smaller blocks, but only one level below. So some even smaller blocks
could still remain selected, and this would result in duplicate erase.

This patch deselects all smaller blocks of all levels below, down to
the smallest size. If the area is covered by one large block, no
other smaller blocks inside are needed.
