rping: Fix server reporting error on exit

Commit e57196c71ddd850e14f3e66355f02786e4914f72
rping: added checks to the return values functions
resulted in the rping server always reporting that
it failed.  Fix this by only failing in the case of
an unexpected termination, and not the result of
the client completing.
