staging: lustre: lnet: Replace semaphore ln_rc_signal with completion
The semaphore ln_rc_signal is used as completion, so convert it to struct completion. Semaphores are going away in the future. Signed-off-by: Binoy Jayan <binoy.jayan@linaro.org> Acked-by: James Simmons <jsimmons@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
