fs: {lock,unlock}_flocks() stubs to prepare for BKL removal

Browse Source 
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.
