ipsec: change wildcard value for any protocol of spd policy

Currently 0 has been used as the wildcard representing ANY type of
protocol. However 0 is valid value of ip protocol (HOPOPT) and therefore
it should not be used as a wildcard. Instead 255 is used which is
guaranteed by IANA to be reserved and not used as a protocol id.

Type: improvement
