lockdep: Do not break user-visible string

Browse Source 
Remove the line-break in the user-visible string and add the
missing space in this error message:

  WARNING: lockdep init error! lock-(console_sem).lock was acquiredbefore lockdep_init

Also:

  - don't yell, it's just a debug warning

  - denote references to function calls with '()'

  - standardize the lock name quoting

  - and finish the sentence.

The result:

  WARNING: lockdep init error: lock '(console_sem).lock' was acquired before lockdep_init().
