bonding: correctly handle out of range parameters for lp_interval

We didn't correctly check cases where the value for lp_interval is not
within the legal range due to a missing table terminator.

This would let userspace trigger a kernel panic by specifying a value out
of range:

echo -1 > /sys/devices/virtual/net/bond0/bonding/lp_interval

Introduced by commit 4325b374f84 ("bonding: convert lp_interval to use
the new option API").
