rust: dma: remove incorrect safety documentation 



Removes a safety requirement that incorrectly states callers must
ensure the device does not access memory while the returned slice
is live, as this method doesn't return a slice.

Fixes: d37a39f6 ("rust: dma: add as_slice/write functions for CoherentAllocation")
