scripts/kernel-doc: fix empty function description section
scripts/kernel-doc mishandles a function that has a multi-line function
short description and no function parameters. The observed problem was
from drivers/scsi/scsi_netlink.c:
/**
* scsi_netlink_init - Called by SCSI subsystem to intialize
* the SCSI transport netlink interface
*
**/
kernel-doc treated the " * " line as a Description: section with only a
newline character in the Description contents. This caused
output_highlight() to complain: "output_highlight got called with no
args?", plus produce a perl call stack backtrace.
The fix is just to ignore Description sections if they only contain "\n".
