bug #41561: AVRDUDE 6.0.1/USBasp doesn't write first bytes of

Browse Source 
flash page
* usbasp.c (usbasp_spi_paged_write): Remove USBASP_BLOCKFLAG_LAST.
It is no longer needed, as we always write full pages now in paged
write mode.

This prevents each flash page from being written twice, where the
second attempt on older devices (ATmega64/128) signalled an immediate
"ready" condition when polling (likely a silicon bug) even though they
were still in progress.  This caused the USBasp firmware to proceed,
and fill the page buffer anew which eventually caused the data
corruption.
