erasure_layout: Remove redundant `verify_range` call from `erase_write`

Previously, verification would be unconditionally completed at the end
of `erase_write` with the non-legacy erase path.

Verification is already handled when writing and erasing chip data; in
`flashrom_image_write` based on `flashctx` options, and in the erase
loop of `erase_write` via `check_erased_range` calls, respectively.

This unnecessary verification added a performance penalty that was not
present with the legacy implementation.

Now, this call to `verify_range` has been removed to improve performance
and more closely reflect the verification done with the legacy path.

This change was tested using the linux_spi programmer to erase and write
to an MT25QL512 chip.
