DMA support is optional in this driver. To enable it, the user
passes the desired DMA channel during the board attach. A timer
is then used by the driver to periodically get the analog input

Since the DMA support is optional, modify the init code so that
it only fails if the DMA channel is unavailable or the DMA buffers
can not be allocated. Don't fail just because the user passed an

In function zram_bvec_write(), previous data at the index is
already freed by function zram_free_page().
When failed to compress or zs_malloc, there is no way to restore old data.
Therefore, free previous data when it's about to update.

Also, no need to check whether table is not empty outside of
