dma-buf: align fd_flags and heap_flags with dma_heap_allocation_data

dma-buf: align fd_flags and heap_flags with dma_heap_allocation_data

dma_heap_allocation_data defines the UAPI as follows:

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

However, dma_heap_buffer_alloc() casts both fd_flags and heap_flags
into unsigned int. We're inconsistent with types in the non UAPI
arguments. This patch fixes it.
