xfrm: Fix xfrm sel prefix length validation
[ Upstream commit b38ff4075a80b4da5cb2202d7965332ca0efb213 ]
Family of src/dst can be different from family of selector src/dst.
Use xfrm selector family to validate address prefix length,
while verifying new sa from userspace.
Validated patch with this command:
ip xfrm state add src 1.1.6.1 dst 1.1.6.2 proto esp spi 4260196 \
reqid 20004 mode tunnel aead "rfc4106(gcm(aes))" \
0x1111016400000000000000000000000044440001 128 \
sel src 1011:1:4::2/128 sel dst 1021:1:4::2/128 dev Port5
