Update key_sa_recordxfer() to use PCPU counters.

NOTE: previously CURRENT usetime was updated every time, when
key_sa_recordxfer() is invoked. RFC 2367 says:

sadb_lifetime_usetime
      For CURRENT, the time, in seconds, when association
      was first used. For HARD and SOFT, the number of
      seconds after the first use of the association until
      it expires.

Rename usetime into firstused and update it only once. Also, now
it is possible to check SA expiration using difference between
SOFT/HARD usetime and CURRENT firstused (this is already done in
key_flush_sad).
