Markus Armbruster e6ab40fee0 qapi: Indent tagged doc comment sections properly
docs/devel/qapi-code-gen demands that the "second and subsequent lines
of sections other than "Example"/"Examples" should be indented".
Commit a937b6aa73 (qapi: Reformat doc comments to conform to current
conventions) missed a few instances, and a few more have crept in
since.  Indent them.

# @YankInstance:
#
# A yank instance can be yanked with the @yank qmp command to recover
# from a hanging QEMU.
#
# Currently implemented yank instances:
#
# - nbd block device: Yanking it will shut down the connection to the
# nbd server without attempting to reconnect.
# - socket chardev: Yanking it will shut down the connected socket.
# - migration: Yanking it will shut down all migration connections.
# Unlike @migrate_cancel, it will not notify the migration process,
# so migration will go into @failed state, instead of @cancelled
# state. @yank should be used to recover from hangs.
#
# Since: 6.0

# @yank:
#
# Try to recover from hanging QEMU by yanking the specified instances.
# See @YankInstance for more information.

# Takes a list of @YankInstance as argument.

# Example:
#
# -> { "execute": "yank",
# "arguments": {
# "instances": [
# { "type": "block-node",
# "node-name": "nbd0" }
# ] } }
