[ Upstream commit 13a0d1088c8fea1565e30a169188b59bdd77759e ]

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.
