When updating a resource, the LwM2M library verified pmin attribute on
all resources/objects in the observer path list and chose the smallest
value. While this make sense for determining the lower-boundary for the
next notification time, it could lead to unnecessary notifications being
generated too early if the updated resource had a higher pmin value
configured on it.
Therefore, when checking notification criteria for an updated resource,
check the pmin value for that resource path and if set and higher than
the lowest pmin value evaluated for the observer list, use it instead.
