winex11: Simplify confusing condition and error messages in wglShareLists.

Mathematically, ((a && b) || b) == b. Moreover, test_sharelists in
dlls/opengl32/tests/opengl.c checks that wglShareLists can share lists
from a source context that has been current.

(cherry picked from commit aa70bdb5d60d643af11feb91fe4367960f85e192)
