Subject: [PATCH] power: supply: mt6370: Fix missing error code in mt6370_chg_toggle_cfo()

When mt6370_chg_field_get() suceeds, ret is set to zero and returning
zero when flash led is still in strobe mode looks incorrect.

Fixes: 233cb8a47d65 ("power: supply: mt6370: Add MediaTek MT6370 charger driver")
