commit 422d2f77803d85477df72f3153e85fd2b8c6b9e9

    batman-adv: Remove needless init of variables on stack
    
    Some variables are overwritten immediatelly in a functions. These don't
    have to be initialized to a specific value on the stack because the value
    will be overwritten before they will be used anywhere.
