navigator: fix home altitude feasibility check 

This includes the following:
- Remove warning/throw_error flag as it is always !home_alt_valid.
- Remove impossible code path when home_alt_valid = false and
  throw_error = false.
- Add home_alt_valid check in second check before using home_alt.
- Only use warning for the second check to allow waypoints below home.
- Don't return early when only warning.
