[Dextrose] [PATCH][dextrose-platform] disable_mesh exit if already disabled

[Martin Abente]

Apparently, powerd's postresume.d scripts are also called
in other saving power situations. Therefore, the script
was endlessly waiting for the mesh to be enable in order
to re disable it.

This patch add this new scenario to the script logic.
