usb: ehci-msm-hsic: Fix unbalanced clock warning
The HSIC controller may be in suspend state in which its clocks
are already disabled. Fix warning given by clock subsystem when
disabling the clocks a second time when the controller's platform
device is removed by first checking if the device is suspended.
