Remove a bogus memset

We get this warning:

    v4l.c:1154:39: warning: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to remove the addressof? [-Wsizeof-pointer-memaccess]

It's correct enough, but ->cap is already zeroed by the previous memset.
Just remove the bogus one.
