[PATCH] Pass sparse the lock expression given to lock annotations

The lock annotation macros __acquires, __releases, __acquire, and __release
all currently throw away the lock expression passed as an argument.  Now
that sparse can parse __context__ and __attribute__((context)) with a
context expression, pass the lock expression down to sparse as the context
expression.  This requires a version of sparse from GIT commit
37475a6c1c3e66219e68d912d5eb833f4098fd72 or later.
