[Mesa-dev] [PATCH 1/2] glx: Avoid calling __glXInitialize() in driReleaseDrawables().

This fixes a regression introduced by commit
a26121f37530619610a78a5fbe5ef87e44047fda (fd.o bug #39219).

Since the __glXInitialize() call should be unnecessary anyway, this is
probably a nicer fix for the original problem too.

NOTE: This is a candidate for the 7.10 and 7.11 branches.
