Core/MMaps: Fix mobs evading when target is out of MMap meshes

Browse Source 
Fix mobs evading when target is out of MMap meshes causes by an overzealous check added in c602220e02 when trying to fix an infinite loop in Recast.
If the target is outside of the MMap mesh (for example very close to a wall which is an un-walkable area with current TrinityCore settings and that might be changed in the future) Detour will not be able to find the height of the poly and getPolyHeight() will return DT_FAILURE | DT_INVALID_PARAM . Most of the time this is ok and can be ignored and it's still better than having the Unit evade.
Fix #23613
