spi: rockchip-sfc: Fix assigned but never used return error codes

Browse Source 
Currently there are two places where the error return variable ret is
being assigned -ETIMEDOUT on timeout errors and this value is not
being returned. Fix this by returning -ETIMEDOUT rather than redundantly
assiging it to ret.

Addresses-Coverity: ("Unused value")
