[PULL 3/8] tests/qtest/ide-test: add a multi-sector ATAPI DMA read test

["Denis V. Lunev" <den@openvz.org>]

test_cdrom_pio_large() already exercises a multi-sector PIO read.
Add the DMA counterpart through the same cdrom_read_impl() helper so
the multi-block ATAPI DMA read path gets equivalent coverage.
