From: Chaitanya Kulkarni <kch@nvidia.com>

[ Upstream commit 06965037ce942500c1ce3aa29ca217093a9c5720 ]

There is only one caller for __blk_account_io_done(), the function
is small enough to fit in its caller blk_account_io_done().

Remove the function and opencode in the its caller
blk_account_io_done().
