hid: intel-ish-hid: Fix uninitialized variable 'rv' in ish_fw_xfer_direct_dma
Fix the uninitialized symbol 'rv' in the function ish_fw_xfer_direct_dma to resolve the following warning from the smatch tool: drivers/hid/intel-ish-hid/ishtp-fw-loader.c:714 ish_fw_xfer_direct_dma() error: uninitialized symbol 'rv'. Initialize 'rv' to 0 to prevent undefined behavior from uninitialized access.
