Alexander Aring 01e8ce0208 dlm: fix user space lkb refcounting ...

[ Upstream commit 2ab3d705ca ]

This patch fixes to check on the right return value if it was the last
callback. The rv variable got overwritten by the return of
copy_result_to_user(). Fixing it by introducing a second variable for
the return value and don't let rv being overwritten.
