HID: hid_reset_resume() needs to be defined only when CONFIG_PM is set

Browse Source 
There is no point of having hid_reset_resume() when CONFIG_PM is
not set, and even the corresponding .reset_resume pointer in hid_driver
struct is properly ifdefed.

Move the definition into the ifdef CONFIG_PM part of the source to avoid

drivers/hid/usbhid/hid-core.c:1337: warning: 'hid_reset_resume' defined but not used
