Replace the call to sdw_ch_mask_to_ch() with a call to hweight32().

sdw_ch_mask_to_ch() is counting the number of set bits. The hweight() family of functions already do this, and they have an advantage of using a bit-counting instruction if it is available on the target CPU. This also fixes a potential infinite loop bug in the implementation of sdw_ch_mask_to_ch().

Applied, thanks
