[PATCH 05/12] ocfs2: properly initial file_lock used for unlock.

[NeilBrown]

Rather than assuming all-zeros is sufficient, use the available API to
initialize the file_lock structure use for unlock.
VFS-level changes will soon make it important that the
list_heads in file_lock are always properly initialized.
