Return early in case of maximum ammount of plugin resolution attempts

[enen92]

Description

At the moment kodi crashes if playing a plugin CFileItem that still has a plugin:// path in the dynPath after the limit of 5 resolution attempts has been reached.

Also, if the plugin:// path being played sets the resolved to an empty path (thus GetDynPath() falls back to path) same issue will occur.

Motivation and Context

Kodi should not crash :)

How Has This Been Tested?

Easiest way to reproduce the problem in Kodi master:

• Install IMDb Trailers video addon from the official repo
• Enter the plugin
• Navigate to coming soon
• Play the trailer of "Trolls: Tour Mundial"
