[PATCH 2/2] w35und: Fix ->configure_filter breakage

[Pekka Enberg]

From: Pekka Enberg <penberg@xxxxxxxxxxxxxx>

Commit 3ac64beecd27400d12cc7afb4108eef26c499f6a ("mac80211: allow
configure_filter callback to sleep") ->configure_filter function
signature. Fix driver breakage by introducing a ->prepare_multicast
operation that returns "mc_count". I'm not sure if the "mc_count > 32"
check is actually needed but lets keep the driver functionally
equivalent for now.
