mtd: rawnand: vf610: disable clk on error handling path in probe
vf610_nfc_probe() does not invoke clk_disable_unprepare() on one error
handling path. The patch fixes that.
Found by Linux Driver Verification project (linuxtesting.org).
Fixes: 6f0ce4dfc5a3 ("mtd: rawnand: vf610: Avoid a potential NULL pointer dereference")
