In vb2_dc_alloc(), get_device() is called to increment the device
reference count. However, if subsequent DMA allocation fails
(vb2_dc_alloc_coherent or vb2_dc_alloc_non_coherent returns error),
the function returns without calling put_device(), causing a device
reference leak.
Add put_device() call in the error path before kfree() to properly
release the device reference acquired earlier.
