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.
