mac80211: Fix loading of rsi_sdio module

Browse Source 
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.

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")
