LU-8017 obd: report correct health state of a node

The patch 16933 that changed the handling of seq_printf
to work with newer kernels introduced a bug in the proc
file that reports the health of a node. The original
code returned immediately after a healthy state was
reported but the bug prevented the immediate return
so a false unhealthy state was always reported instead.
