mac80211: Fix loading of rsi_sdio module
When CONFIG_PM was not set rsi_sdio_reinit_device() was not compiled into the driver but referenced. This is a backport form the mainline Linux kernel. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

+Subject: rsi: move rsi_sdio_reinit_device() out of CONFIG_PM
+
+This function is generic. It doesn't contain wowlan specific code.
+It should not be under CONFIG_PM. This patch resolves compilation
+errors observed when CONFIG_PM flag is disabled.
+
+Reported-by: kbuild test robot <fengguang.wu@intel.com>
+Fixes: ef71ed0608c ("rsi: sdio: Add WOWLAN support for S5 shutdown state")
+Fixes: a24e35fcee0 ("rsi: sdio: Add WOWLAN support for S4 hibernate state")
+Fixes: e1ced6422a3 ("rsi: sdio: add WOWLAN support for S3 suspend state")
