The lock annotations used on spinlocks and rwlocks currently use
__{acquires,releases}(spinlock_t) and __{acquires,releases}(rwlock_t),
respectively. This loses the information of which lock actually got
acquired or released, and assumes a different type for the parameter of
__acquires and __releases than the rest of the kernel. While the current
implementations of __acquires and __releases throw away their argument,
this will not always remain the case. Change this to use the lock
parameter instead, to preserve this information and increase consistency in
usage of __acquires and __releases.
