[PATCH upstream for stable 8/8]staging: vt6656: 64bit fixes: vCommandTimerWait change calculation of timer.

upstream commit
70e227790d4ee4590023d8041a3485f8053593fc

Tested on kernel 2.6.35, 3.0, 3.2, 3.5 & 3.7

staging: vt6656: 64bit fixes: vCommandTimerWait change calculation of timer.
    
The timer appears to run too fast/race on 64 bit systems.
    
Using msecs_to_jiffies seems to cause a deadlock on 64 bit.
    
A calculation of (MSecond * HZ) / 1000 appears to run satisfactory.
    
Change BSSIDInfoCount to u32.
    
After this patch the driver can be successfully connect on little endian 64/32 bit systems.
