platform/x86: asus-wmi: add missing pci_dev_put() in asus_wmi_set_xusb2pr()



[ Upstream commit d0cdd85046b15089df71a50548617ac1025300d0 ]

pci_get_device() will increase the reference count for the returned
pci_dev. We need to use pci_dev_put() to decrease the reference count
before asus_wmi_set_xusb2pr() returns.
