dediprog: wait for spi bulk read xfers to finish

dediprog_bulk_read_poll()'s finish argument allows it to be used in two
distinct cases: where dediprog_bulk_read_poll will be called as part of
a loop (finish=0) and where dediprog_bulk_read_poll should wait for all
outstanding transfers to finish (finish=1).  In both cases,
dediprog_bulk_read_poll() calls libusb to process events with a 10
second timeout.

After dediprog_spi_bulk_read() has queued the last transfers, it calls
dediprog_bulk_read_poll() with finish=0 when it should be finish=1.
finish=0 just happens to work because frequently the transfers finish in
the 10 second timeout.
