dmaengine: sh: Discard pm_runtime_put() return value

Browse source 
Clobbering an error value to be returned from shdma_tx_submit() with
a pm_runtime_put() return value is not particularly useful, especially
if the latter is 0, so stop doing that.

This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.
