usb: otg: use try_module_get in all usb_get_phy functions and add missing module_put

In patch "5d3c28b usb: otg: add device tree support to otg library"
devm_usb_get_phy_by_phandle() was added. It uses try_module_get() to lock the
phy driver in memory. The corresponding module_put() is missing in that patch.

This patch adds try_module_get() to usb_get_phy() and usb_get_phy_dev().
Further the missing module_put() is added to usb_put_phy().
