RPi Bugfix: False Hardware Failure indication

Was finally able to successfully recreate conditions to consistently
cause 'HARDWARE FAILURE RADIO NOT RESPONDING' messages on RPI master
node:
1: Using RPi B2.0 with Raspbian 4.1.20+ armv61
2. Using 2 matching nrf24l01 non-PA modules w/ext antenna
3. Using RF24Gateway + RF24Ethernet
4. Using Arduino Due as RF24Ethernet node

Test scenario: Mesh working normally for very long periods of time.
Re-introduced an old node using Arduino Due. Immediately started
noticing error msgs on master node.

Solution: Increasing the wait time from 85 to 95ms seems to prevent
false indications of hardware failures. It appears, the code was just
not waiting long enough.
