libertas-related slab corruption

Description

When unloading the libertas_sdio module or doing suspend/resume, slab corruption is consistently encountered.

We are using the SLAB allocator. SLUB has better diagnostics in these cases, but when switching to SLUB, no corruption is detected.

kmemcheck doesn't find anything.

Seems to be a 2.6.35 regression, did not happen in 2.6.31.
