Mark Johnston 1c732c8591 dummynet: Fix socket option length validation for IP_DUMMYNET3
The socket option handler tries to ensure that the option length is no
larger than some reasonable maximum, and no smaller than sizeof(struct
dn_id).  But the loaded option length is stored in an int, which is
converted to an unsigned integer for the comparison with a size_t, so
negative values are not caught and instead get passed to malloc().

Change the code to use a size_t for the buffer size.
