Wesley Hershberger 9dbfd4e28d block: Drop detach_subchain for bdrv_replace_node 
Detaching filters using detach_subchain=true can cause segfaults as
described in #3149.

More specifically, this was observed when executing concurrent
block-stream and query-named-block-nodes. block-stream adds a
copy-on-read filter as the main BDS for the blockjob; that filter was
dropped with detach_subchain=true but not unref'd until the the blockjob
was free'd. Because query-named-block-nodes assumes that a filter will
always have exactly one child, it caused a segfault when it observed the
detached filter. Stacktrace:

As discussed in 20251024-second-fix-3149-v1-1-d997fa3d5ce2@canonical.com,
a filter should not exist without children in the first place; therefore,
drop the parameter entirely as it is only used for filters.

This is a partial revert of 3108a15cf0.

After this change, a blockdev-backup job's copy-before-write filter will
hold references to its children until the filter is unref'd. This causes
an additional flush during bdrv_close, so also update iotest 257.
