net: dropreason: reformat the comment fo skb drop reasons
To make the code clear, reformat the comment in dropreason.h to k-doc style. Now, the comment can pass the check of kernel-doc without warnning: $ ./scripts/kernel-doc -v -none include/linux/dropreason.h include/linux/dropreason.h:7: info: Scanning doc for enum skb_drop_reason Signed-off-by: Menglong Dong <imagedong@tencent.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
