This CL reverts the changes made in golang/go#11299.
Allowing creation of multiple contexts break the case of multiple
third party packages depending on the al bindings. These packages
need to make sure that there is a valid current context or initiate
and make a context current. Packages racing to create and make a
context current is what we would like to avoid.
Therefore, al bindings will support only a single context that is
initiated during OpenDevice.
Fixesgolang/go#11385.
