block: skip start/end time stamping for passthrough IO
commit 41fa722239b4 ("blk-mq: do not include passthrough requests in I/O
accounting")' disables I/O accounting for passthrough requests. Since tools
like 'iostat' do not show anything useful for passthrough I/O, it's
wasteful to do start/end time-stamping. So do away with that.
Avoiding the time-stamping improves the I/O performance by ~7%
