Potential thread safety issue during initialisation of plugin

Looking at a PR which has been integrated earlier for the SMART plugin, and more specifically at commit bf7c332 and commit dada577 which have been added to comply with @lmroz comment r73497782, the same code should be integrated into interface collector plugin

@obourdon Thank you for reporting this issue. It should be carefully investigated.

This plugin uses sticky routing strategy, so concurrency count is set to 1, what means there is no possibilities to use a single plugin instance by two tasks.

There is also an issue to provide Init() once function behavior to plugin lib to make easier manage initialization in plugins which require that - 👉 https://github.com/intelsdi-x/snap-plugin-lib-go/issues/79

Based on above, I will close this issue. Of course, please do not hesitate to re-open if you notice that this issue is still valid in some circumstances. Thank You.
