wlcore: sdio: check for valid platform device data before suspend
the wl pointer can be null In case only wlcore_sdio is probed while no WiLink module is successfully probed, as in the case of mounting a wl12xx module while using a device tree file configured with wl18xx related settings. In this case the system was crashing in wl1271_suspend() as platform device data is not set. Make sure wl the pointer is valid before using it.
