[PATCH v6 3/3] dmaengine: dw-axi-dmac: Remove not useful void return function statements

[Khairul Anuar Romli <karom.9560@gmail.com>]

The dw_axi_dma_set_hw_channel() function is declared as void, so an
explicit `return;` at the end is unnecessary. Control flow naturally
returns to the caller once the function ends. Removing it cleans up the
code and aligns with kernel style guidelines without changing
functionality.

This fix resolves a coding style issue introduced by
- 'commit 32286e279385 ("dmaengine: dw-axi-dmac: Remove free slot check
   algorithm in dw_axi_dma_set_hw_channel")'.

This unnecessary return were detected with the help of the checkpatch.pl
analysis tool with --strict --file option.
