Mark Johnston 10eb2a2bde ipsec: Validate the protocol identifier in ipsec4_ctlinput() 
key_allocsa() expects to handle only IPSec protocols and has an
assertion to this effect.  However, ipsec4_ctlinput() has to handle
messages from ICMP unreachable packets and was not validating the
protocol number.  In practice such a packet would simply fail to match
any SADB entries and would thus be ignored.
