checkpatch: always check block comment styles
Some of the block comment tests that are used only for networking are
appropriate for all patches.
For example, these styles are not encouraged:
/*
block comment without introductory *
*/
and
/*
* block comment with line terminating */
Remove the networking specific test and add comments.
There are some infrequent false positives where code is lazily
commented out using /* and */ rather than using #if 0/#endif blocks
like:
/* case foo:
case bar: */
case baz:
