fs: {lock,unlock}_flocks() stubs to prepare for BKL removal
The lock structs are currently protected by the BKL, but are accessed by code in fs/locks.c and misc file system and DLM code. These stubs will allow all users to switch to the new interface before the implementation is changed to a spinlock.
