sm501fb: don't return zero on failure path in sm501fb_start()
[ Upstream commit dc85e9a87420613b3129d5cc5ecd79c58351c546 ]
If fbmem iomemory mapping failed, sm501fb_start() breaks off
initialization, deallocates resources, but returns zero.
As a result, double deallocation can happen in sm501fb_stop().
