char: imx-rngc: fix clk_disable_unprepare missing in error path 

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I9K8D1



--------------------------------

Function clk_prepare_enable(rngc->clk) is called in imx_rngc_probe, but
clk_disable_unprepare(rngc->clk) is missing in error path. Use goto
exchange return to fix it.

Fixes: cd1da72d ("hwrng: imx-rngc - Moving IRQ handler registering after imx_rngc_irq_mask_clear()")
