[PATCH v4 09/13] USB: ch341: fix coding style

[Grigori Goronzy]

No functional change.  The following adjustments were made to be more in
line with official coding style and to be more consistent.

Stop mixing tabs and spaces for alignment.  Stop putting labels and
statements into the same line.  Use braces consistently for a single
statement.

v2: drop most changes, particularly indentation changes.
