[PATCH AUTOSEL for 3.18 42/53] sm501fb: don't return zero on failure path in sm501fb_start()

From: Alexey Khoroshilov [ 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().
