raw/ifpga: fix integer overflow for N3000

Expression "tx_chunks * ctx->dma_buf_size" in dma_fpga_to_fpga()
is evaluated using 32-bit arithmetic, which would overflow
 potentially. Change tx_chunks to type "uint64_t" to avoid such
issue.

Coverity issue: 379203
Fixes: 7d63899a5c19 ("raw/ifpga: add N3000 AFU driver")
