Subject: [PATCH v5 3/9] completion: Change the prefix of lock name for completion variable

CONFIG_LOCKDEP_COMPLETIONS uses "(complete)" as a prefix of lock name
for completion variable.

However, "complete" is a verb or adjective and lock symbol names
should be nouns. Use "(completion)" instead, for normal completions.
