Gavrilov Ilia 8b409c7cf3 net: kcm: fix incorrect parameter validation in the kcm_getsockopt) function
[ Upstream commit 3ed5f41513 ]

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.
