Meng Li d0243bbd5d drivers core: Free dma_range_map when driver probe failed ...

There will be memory leak if driver probe failed. Trace as below:
  backtrace:
    [<000000002415258f>] kmemleak_alloc+0x3c/0x50
    [<00000000f447ebe4>] __kmalloc+0x208/0x530

    [<000000006356866a>] platform_dma_configure+0x2c/0x40
    ......
    [<000000000afcf9b5>] ret_from_fork+0x10/0x3c

This issue is introduced by commit e0d072782c73("dma-mapping:
introduce DMA range map, supplanting dma_pfn_offset "). It doesn't
free dma_range_map when driver probe failed and cause above
memory leak. So, add code to free it in error path.

Fixes: e0d072782c ("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset ")
