[PATCH] raw/ifpga: avoid potential integer overflow

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") Signed-off-by: Wei Huan
