Yu Kuai 3c9a4070ba md/raid10: don't call bio_start_io_acct twice for bio which experienced read error
[ Upstream commit 7cddb055bf ]

handle_read_error() will resumit r10_bio by raid10_read_request(), which
will call bio_start_io_acct() again, while bio_end_io_acct() will only
be called once.

Fix the problem by don't account io again from handle_read_error().

Fixes: 528bc2cf2f ("md/raid10: enable io accounting")
