[PATCH 01/20] filelock: split common fields into struct file_lock_core

[Jeff Layton]

In a future patch, we're going to split file leases into their own
structure. Since a lot of the underlying machinery uses the same fields
move those into a new file_lock_core, and embed that inside struct
file_lock.
