aaron.sun a748e54e88 [drm]: Fix drm handle issue ...

There is a bug when using single drm allocator device for all buffers:

Sample:
1. external fd a is import to mpp_buffer and get handle B / fd b.
2. external fd a is import to mpp_buffer again and get handle B / fd c.
   NOTE: The handle is the same in mpp for drm allocator is the same
   and the handle ref_count is not increased.
4. release fd b and handle B. (NOTE: The handle B is released in kernel)
5. mmap fd c by handle B. (Crash on getting handle B in kernel)

So we should reacquire handle for fd c when it need mmap or free.
