[PATCH v2 4/6] spi: rockchip: Fix runtime resume error handling

[Heiko Stuebner <heiko@sntech.de>]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

When enabling the apb-clock any error does get handled, but when an
error happens enabling the spiclk itself, only the apb-clock is disabled
but the function then returns successful.

Fix this by also reporting the error on enabling the second clock.
