Ncp: Clear the "prop changed flags" after successful message sent. (#397)

This commit updates how the `mChangedFlags` (which keeps track of
properties which are changed) is cleared for `RESET_REASON` and
`IP6_LL_ADDR` to ensure that the notification message is
successfully queued/sent before clearing the flag.
