Fixing small glitch in FW-74.
Ensure radio reset delay is respected by turning delay variable volatile. Only a problem when compiler optimizes away the variable.
Important changes to the IEEE802.15.4e state machine:
- Fixing race condition when radio is started after the radiotimer is. Sometimes the radiotimer's rollover event (which messes with the radio) would happen as the radio was initialized, causing a deadlock.
- Fixing typo in state name during sync (!)
