libertas: fix invalid access

Browse Source 
card->priv must not be accessed after lbs_remove_card() was called
as lbs_remove_card() frees card->priv via free_netdev().

For libertas_sdio this is a regression introduced by 23b149c189.
The correct fix to the issue described there is simply to remove the
assignment. This flag is set at the appropriate time inside
lbs_remove_card anyway.
