Repair kernel-doc notation in a few places to make it conform to
the expected format.
Fixes the following kernel-doc warnings:
flow.c:296: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
* Parse vlan tag from vlan header.
flow.c:296: warning: missing initial short description on line:
* Parse vlan tag from vlan header.
flow.c:537: warning: No description found for return value of 'key_extract_l3l4'
flow.c:769: warning: No description found for return value of 'key_extract'
