libertas: fix card cleanup order in SDIO driver
The SDIO driver sets the surpriseremoved flag before calling lbs_remove_card. With IEEE PS enabled, lbs_remove_card must issue a command to exit IEEE PS mode, however with that flag set the command path is blocked and the card is never taken out of IEEE PS mode. This step is required to ensure that the driver can be reloaded. This patch moves the setting of surpriseremoved after lbs_remove_card is called. Tested with V9 firmware by ensuring that IEEE PS is disabled when the driver is removed. Reloading the driver is not fully tested due to a separate issue with module reload in the SDIO driver, however this patch at least leaves the card in a better state when we bring the driver down.
