[PATCH] checkpatch.pl: Fix checkpatch false positive due to ternary operator break

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: David Ertman <davidx.m.ertman@intel.com>

Using the intuitive breaking of a ternary operator used in the
initialization of a variable in its declaration:

type var = FOO ?
           BAR :
           FEE;

is causing a checkpatch warning:
"WARNING:SPACING: networking uses a blank line after declarations"

Checkpatch is checking for the ternary operators at the beginning of the
lines after the initial break like the following:

type var = FOO
           ? BAR
           : FEE;

Change checkpatch so that it is checking fot the correct breaking of ternary
operators used in networking variable declaration/initialization.
