block: Don't allow an atomic write be truncated in blkdev_write_iter()
[ Upstream commit 2cbd51f1f8739fd2fdf4bae1386bcf75ce0176ba ]
A write which goes past the end of the bdev in blkdev_write_iter() will
be truncated. Truncating cannot tolerated for an atomic write, so error
that condition.
Fixes: caf336f81b3a ("block: Add fops atomic write support")
