docs tests: Fix use of migrate_set_parameter

Browse Source 
docs/multi-thread-compression.txt uses parameter names with
underscores instead of dashes.  Wrong since day one.

docs/rdma.txt, tests/qemu-iotests/181, and tests/qtest/test-hmp.c are
wrong the same way since commit cbde7be900 (v6.0.0).  Hard to see,
as test-hmp doesn't check whether the commands work, and iotest 181
appears to be unaffected.

Fixes: 263170e679 (docs: Add a doc about multiple thread compression)
Fixes: cbde7be900 (migrate: remove QMP/HMP commands for speed, downtime and cache size)

The following are the default settings:
compress: off
compress_threads: 8
decompress_threads: 2
compress_level: 1 (which means best speed)
compress-threads: 8
decompress-threads: 2
compress-level: 1 (which means best speed)
So, only the first two steps are required to use the multiple
thread compression in migration. You can do more if the default

First, set the migration speed to match your hardware's capabilities:
