power: supply: qcom_pmi8998_charger: fix uninitialized variable
smatch warnings:
drivers/power/supply/qcom_pmi8998_charger.c:565 smb2_status_change_work() error: uninitialized symbol 'usb_online'.
usb_online is used uninitialized whenever smb2_get_prop_usb_online()
returns a negative value.
Thus, fix the issue by initializing usb_online to 0.
Fixes: 8648aeb5d7b7 ("power: supply: add Qualcomm PMI8998 SMB2 Charger driver")
