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

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
