Patch for missing OpenGL locks in dlls/wined3d/context.c

When running Mass Effect 1.0 with Wine 1.1.18 on RHEL 5 and Core 2 Duo T7500,
it frequently crashes with "Xlib: unexpected async reply", caused by multiple
threads to access the same GLX surface. Enabling tracing for d3d shows that
this happens at least in the vincinity of context_bind_fbo, and
context_apply_attachment_filter_states (dlls/wined3d/context.c). These
functions lack OpenGL locking via ENTER_GL()/LEAVE_GL().

Applying the attached patch apparently fixes the problem.
