LibGL: Check that texture name is allocated before marking it as free

Browse source 
glDeleteTextures previously did not check that the texture name was
allocated by glGenTextures before adding it to the free texture name
list.

This means that if you delete a texture twice in a row, the name will
appear twice in the free texture list, making glGenTextures return the
same texture name twice in a row.
