completion: Drop init_completion define

Changeset cd8084f91c02 ("locking/lockdep: Apply crossrelease to completions")
added a CONFIG_LOCKDEP_COMPLETE (that was later renamed to
CONFIG_LOCKDEP_COMPLETIONS).

Such changeset renamed the init_completion, and add a macro
that would either run a modified version or the original code.

However, such code reported too many false positives. So, it
ended being dropped later on by
changeset e966eaeeb623 ("locking/lockdep: Remove the cross-release locking checks").

Yet, the define remained there as just:

	 #define init_completion(x) __init_completion(x)

Get rid of the define, and return __init_completion() function
to its original name.

Fixes: e966eaeeb623 ("locking/lockdep: Remove the cross-release locking checks")
