Staging: vt6656: Combined nested conditions 

This patch reduces the level of indentation in bssdb.c of the vt6656
driver by transforming nested conditions to a series of logical
conjunctions. E.g.

if (cond1) {
        if (cond2) {
                block();
        }
}

is transformed to

if (cond1 && cond2) {
        block();
}
