staging: wilc1000: Fix problem with wrong vif index
commit 0e490657c7214cce33fbca3d88227298c5c968ae upstream.
The vif->idx value is always 0 for two interfaces.
wl->vif_num = 0;
loop {
...
vif->idx = wl->vif_num;
...
wl->vif_num = i;
....
i++;
...
}
At present, vif->idx is assigned the value of wl->vif_num
at the beginning of this block and device is initialized
based on this index value.
In the next iteration, wl->vif_num is still 0 as it is only updated
later but gets assigned to vif->idx in the beginning. This causes problems
later when we try to reference a particular interface and also while
configuring the firmware.
This patch moves the assignment to vif->idx from the beginning
of the block to after wl->vif_num is updated with latest value of i.
Fixes: commit 735bb39ca3be ("staging: wilc1000: simplify vif[i]->ndev accesses")
