xfs: add an error tag to inject a ->writeback_submit() failure
The only in-tree way for xfs_writeback_submit() to fail is a failing
xfs_reflink_convert_cow(), which requires a shared (reflinked) CoW
extent. There was previously no way to exercise that failure path
from userspace, which made it hard to write an xfstest for it, e.g.
for "iomap: don't resubmit an ioend after ->writeback_submit()
failed".
Add XFS_ERRTAG_WB_COW_CONVERT_ERROR to force xfs_reflink_convert_cow()
to fail with -EIO, so that ->writeback_submit() failure and its
callers' error handling can be exercised with error injection alone,
without needing a corrupted or racy COW fork.
