[ Upstream commit 4f666675cdff0b986195413215eb062b7da6586f ]
When powering down a SDIO connected card during suspend, make sure to call
into the generic lbs_suspend() function before pulling the plug. This will
make sure the card is successfully deregistered from the system to avoid
communication to the card starving out.
Fixes: 7444a8092906 ("libertas: fix suspend and resume for SDIO connected
cards")
