BTW, this problem is repeated in several places throughout this driver.
For instance, look for 'user_rmmod' (why? you shouldn't need to treat
module unload differently...) and the work structs (and corresponding
'saved_adapter' and 'iface_flags') used for PCIe function-level reset
and SDIO reset.

Hopefully either Marvell's or my cleanups can move to get rid of these
anti-patterns soon...
