ipmr: Copy option to correct variable
Cited commit mistakenly copied provided option to 'val' instead of to
'mfc':
```
- if (copy_from_user(&mfc, optval, sizeof(mfc))) {
+ if (copy_from_sockptr(&val, optval, sizeof(val))) {
```
Fix this by copying the option to 'mfc'.
selftest router_multicast.sh before:
$ ./router_multicast.sh

smcroutectl: failed removing multicast route, does not exist.
