[ Upstream commit 05684fd583e1acc34dddea283838fbfbed4904a0 ]
Before this patch, we use value from 2 seconds ago to decide
whether we should do lc calibration.
Although this don't happen frequently, fix flow to the way it should be.
Fixes: 7ae7784ec2a8 ("rtw88: 8822c: add LC calibration for RTL8822C")
