xl/zones: return errNoHealRequired when no heal is required (#8821)

Browse Source 
Zone abstraction of object layer was returning `nil`
incorrectly under situations where disk healing is
not required. Returning `nil` is considered as healing
successful, which leads to unexpected ReloadFormat()
peer notification calls during startup.

This PR fixes this behavior properly for zones.
