[PATCH] USB: fix pm patches with CONFIG_PM off part 2

With CONFIG_PM=n:

drivers/built-in.o(.text+0x1098c): In function `hub_thread':
drivers/usb/core/hub.c:2673: undefined reference to `.dpm_runtime_resume'
drivers/built-in.o(.text+0x10998):drivers/usb/core/hub.c:2674: undefined reference to `.dpm_runtime_resume'

Please, never ever ever put extern decls into .c files.  Use the darn header
files :(
