Subject: regulator: stm32-vrefbuf: fix check on ready flag

From: Fabrice Gasnier <[email protected]>

commit f63248fac563125fd5a2f0bc780ce7a299872cab upstream.

stm32_vrefbuf_enable() wrongly checks VRR bit: 0 stands for not ready, 1 for ready. It currently checks the opposite.
This makes enable routine to exit immediately without waiting for ready flag.
