net: Make the copy length in af_packet sockopt handler unsigned

fixed upstream in commit b7058842c940ad2c08dd829b21e5c92ebe3b8758 in a different way

The length of the to-copy data structure is currently stored in
a signed integer. However many comparisons are done with sizeof(..)
which is unsigned. It's more suitable for this variable to be unsigned
to make these comparisons more naturally right.
