Alexander Motin efdfb14fc8 Remove pool io kstats ... This mostly reverts "3537 want pool io kstats" commit of 8 years ago. From one side this code using pool-wide locks became pretty bad for performance, creating significant lock contention in I/O pipeline. From another, there are more efficient ways now to obtain detailed statistics, while this statistics is illumos-specific and much less usable on Linux and FreeBSD, reported only via procfs/sysctls. This commit does not remove KSTAT_TYPE_IO implementation, that may be removed later together with already unused KSTAT_TYPE_INTR and KSTAT_TYPE_TIMER.
