[PATCH 2/3] hw/scsi/esp: Let ESPDMAMemoryReadWriteFunc take void pointer and size_t

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

The ESPDMAMemoryReadWriteFunc handlers end calling
dma_memory_read/write, which both take void pointers (since
introduced in commit d86a77f8). The ESPDMAMemoryReadWriteFunc
handlers can take a void pointer too.

All calls to these handlers in hw/scsi/esp.c use an unsigned
length. Use size_t type.
