[PATCH] usb_wwan: fix build error in play_delayed.

From: Tao Ma

There is a build error in today's linus tree.
drivers/usb/serial/usb_wwan.c: In function â??play_delayedâ??:
drivers/usb/serial/usb_wwan.c:702: error: â??struct dev_pm_infoâ?? has no member named â??usage_countâ??
The reason is that usage_count is wrapped with macro CONFIG_PM_RUNTIME
now in dev_pm_info.

So use the corresponding pm_runtime_get_noresume instead.
