crypto: rk3288 - fail ahash requests on HASH idle timeout

Browse source

rk_hash_run() waits for RK_CRYPTO_HASH_STS to become idle after the
final DMA transfer, but ignores the poll result. If the hash engine
never becomes idle, the driver still reads the digest registers and
finalizes the request with the previous success value.

Store the poll result and finalize the request with the timeout error
before reading the digest registers.
