ovl: change ovl_create_index() to take dir locks
ovl_copy_up_workdir() currently take a rename lock on two directories,
then use the lock to both create a file in one directory, perform a
rename, and possibly unlink the file for cleanup. This is incompatible
with proposed changes which will lock just the dentry of objects being
acted on.
This patch moves the call to ovl_create_index() earlier in
ovl_copy_up_workdir() to before the lock is taken.
ovl_create_index() then takes the required lock only when needed.
