[PATCH] rust: dma: drop placeholder TODO comment

[Melih Emik <melihemik@noirlang.tr>]

The comment above Coherent already describes the outstanding design

considerations around device resource lifetime.

Drop the standalone placeholder TODO marker and keep the explanatory

text, including a minor wording fix.

No functional change intended.
