Currently, function nvgpu_bitmap_allocator_init() initializes bitmap with length=0 but will fail in alloc(). Function alloc() allocates len=0 bitmap and next request also starts from same address. However, rbtree only holds zero length allocation. This patch adds length = 0 check in nvgpu_bitmap_allocator_init() and alloc() functions.
