regulator: mt6358: Fix incorrect VCN33 sync error message

After syncing the enable status of VCN33_WIFI to VCN33_BT, the driver
will disable VCN33_WIFI. If it fails it will error out with a message.
However the error message incorrectly refers to VCN33_BT.

Fix the error message so that it correctly refers to VCN33_WIFI.
