BACKPORT: FROMLIST: dma-buf/heaps: Correct the types of fd_flags and heap_flags

dma_heap_allocation_data defines the UAPI as follows:

 struct dma_heap_allocation_data {
        __u64 len;
        __u32 fd;
        __u32 fd_flags;
        __u64 heap_flags;
 };

But dma heaps are casting both fd_flags and heap_flags into
unsigned long. This patch makes dma heaps - cma heap and
system heap have consistent types with UAPI.
