Subject: [XFRM]: Fix statistics.
o Outbound sequence number overflow error status
is counted as XfrmOutStateSeqError.
o Additionaly, it changes inbound sequence number replay
error name from XfrmInSeqOutOfWindow to XfrmInStateSeqError
to apply name scheme above.
o Inbound IPv4 UDP encapsuling type mismatch error is wrongly
mapped to XfrmInStateInvalid then this patch fiex the error
to XfrmInStateMismatch.
