Gavrilov Ilia 3ed5f41513 net: kcm: fix incorrect parameter validation in the kcm_getsockopt) function 
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.
