block: open code __blk_account_io_start()
[ Upstream commit e165fb4dd6985b37215178e514a2e09dab8fef14 ]
There is only one caller for __blk_account_io_start(), the function
is small enough to fit in its caller blk_account_io_start().
Remove the function and opencode in the its caller
blk_account_io_start().
