[PATCH] spi: spi-rockchip: Fix missing unwind goto in rockchip_sfc_probe()

[Li Lanzhe <u202212060@xxxxxxxxxxx>]

If devm_request_irq() fails, then we are directly return 'ret' without 
clk_disable_unprepare(sfc->clk) and clk_disable_unprepare(sfc->hclk).

Fix this by changing direct return to a goto 'err_irq'.
