totemconfig: Change default FAIL_TO_RECV_CONST

Browse Source 
Previous default (50) was too low for most modern switch hardware. This
may trigger abort because the aru doesn't increase for 50 token
rotations combined with a defect in how failed to recv conditions are
handled.  By increasing this tunable, the condition should no longer
trigger the errant code.
