spi: rzv2h-rspi: Fix DMA transfer error handling for signal interruption
wait_event_interruptible_timeout() can return a negative error code when
interrupted by a signal. The original code treated all non-zero return
values as success, which would incorrectly synchronize DMA channels and
return 0 instead of propagating the interruption error.
Fixes: fa08b566860b ("spi: rzv2h-rspi: add support for DMA mode")
