[PATCH -next] power: supply: mt6370: Fix return value check in mt6370_chg_probe()

[Yang Yingliang]

If create_singlethread_workqueue() fails, it returns a null pointer,
replace IS_ERR() check with NULL pointer check.

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