Gavrilov Ilia 7089428a1a net/x25: fix incorrect parameter validation in the x25_getsockopt() function
[ Upstream commit d6eb8de201 ]

The 'len' variable can't be negative when assigned the result of
'min_t' because all 'min_t' parameters are cast to unsigned int,
and then the minimum one is chosen.

To fix the logic, check 'len' as read from 'optlen',
where the types of relevant variables are (signed) int.
