[PATCH 1/3] cbus: tahvo: Fix build breakage caused by deprecated initializer removal

[Jarkko Nikula <jhnikula@gmail.com>]

Use DEFINE_SPINLOCK() for static spinlock initialization as the commit
d04fa5a "locking: Remove deprecated lock initializers" removes the
deprecated SPIN_LOCK_UNLOCKED. Since tahvo_lock is not used elsewhere than
tahvo.c it can be removed from tahvo.h too.
