    basetransform: Check if meta transform_func is NULL before using it

    An untested pointer segfaulted in webkit while playing video
    on imx6 sabrelite. It turned out that the imx plugin didn't
    implement the meta transform function.

    The following GST_DEBUG trace was visible:
    gstbasetransform.c:1779:foreach_metadata:<conv2> copy metadata
                                                    GstImxVpuBufferMetaAPI

    Thread 26 vqueue:src received signal SIGSEGV, Segmentation fault.

    (gdb) bt
     0x00000000 in ?? ()
     0x73f8d7d8 in foreach_metadata (inbuf=0xc9b020, meta=0x474b2490,
                      user_data=<optimized out>) at gstbasetransform.c:1781
