ALSA: docs: Fix code block indentation in ALSA driver example

Sphinx reports htmldocs warnings:

Documentation/sound/kernel-api/writing-an-alsa-driver.rst:3997: WARNING: Literal block expected; none found.
Documentation/sound/kernel-api/writing-an-alsa-driver.rst:4004: WARNING: Literal block expected; none found.
Documentation/sound/kernel-api/writing-an-alsa-driver.rst:4009: WARNING: Unexpected indentation.
Documentation/sound/kernel-api/writing-an-alsa-driver.rst:4035: WARNING: Literal block expected; none found.

These are due to indentation of example driver snippets which is outside
the code block scope.

Fix these by indenting code blocks in question to the scope.
