mesa: Fix valid texture target test in _mesa_GetTexLevelParameteriv()

Browse source 
_mesa_max_texture_levels() is also used to test valid texture target
in _mesa_GetTexLevelParameteriv(). GL_TEXTURE_CUBE_MAP is not allowed
as texture target in glGetTexLevelParameter(). So, this should throw
GL_INVALID_ENUM error.

Few other functions which use _mesa_max_texture_levels() like
getcompressedteximage_error_check() and getteximage_error_check()
also don't accept GL_TEXTURE_CUBE_MAP.

Above fix makes piglit fbo-cubemap test to fail. This is because of
incorrect texture target passed to _mesa_max_texture_levels() in
framebuffer_texture(). Fixing that as well

Note: This is a candidate for the stable branches
