net/packet: fix overflow in check for tp_frame_nr
[ Upstream commit 8f8d28e4d6d815a391285e121c3a53a0b6cb9e7b ]
When calculating rb->frames_per_block * req->tp_block_nr the result
can overflow.
Add a check that tp_block_size * tp_block_nr <= UINT_MAX.
Since frames_per_block <= tp_block_size, the expression would
never overflow.
