* usbasp.c (usbasp_tpi_paged_load): Calculate correct 

buffer address.
* usbasp.c (usbasp_tpi_paged_write): Calculate correct
buffer address; don't issue a SECTION_ERASE command for
each page (a CHIP_ERASE has been done before anyway);
remove the code that attempted to handle partial page
writes, as all writes are now done with a full page.
