[PATCH 03/12] staging: wilc1000: take vif instead of drv in hostIFthread

[Glen Lee <glen.lee@atmel.com>]

In the first patch, we sent vif to hostIFthread. we can use vif instead of
drv in the all functions which handle the commands from cfg operations.
Change first argument host_if_drv with wilc_vif and use hif_drv of wilc_vif.
Pass vif to the functions as well.
In case of timer callback functions, set vif to the data and use vif instead
of hif_drv.
Lastly, initialize u32RcvdAssocRespInfoLen since changing hif_drv with vif
causes one uninitialied build warning.
Now we have vif that currently being used so we can use interface index of
wilc_vif to send to wilc device.
