[PATCH v2 7/7] block: remove dead metadata handling from the async direct I/O path

Since commit 2729a60bbfb9 ("block: don't silently ignore metadata for
sync read/write"), blkdev_direct_IO() sends every IOCB_HAS_METADATA
request to __blkdev_direct_IO(). Remove the now unreachable metadata
mapping in __blkdev_direct_IO_async() and the unmap in its completion
handler.
No functional change.
