usb: chipidea: host: Only disable the vbus regulator if it is not NULL

Commit 40ed51a4b (usb: chipidea: host: add vbus regulator
control) introduced a smatch complaint because regulator_disable() is called
without checking whether ci->platdata->reg_vbus is not NULL.

Fix this by adding the check.

This patch is needed for 3.12 stable
