[PATCH v3 1/5] block: use blkdev_iov_iter_get_pages status for errors

[Keith Busch <kbusch@meta.com>]

From: Keith Busch <kbusch@kernel.org>

blkdev_iov_iter_get_pages() can return various error values, including
EIO, EFAULT, and ENOMEM. Set the actual reported status so user space
can know a little more on why an operation failed.
