[PATCH] kernelscan: fix variable shadowing warning

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Cppcheck is warning about variable name shadowing. Fix this by
renaming the top level variable 'patterns' to 'klog_patterns'.

Cleans up cppcheck warning:
src/utilities/kernelscan.c:352:16: style: Local variable 'patterns'
shadows outer variable [shadowVariable]
 klog_pattern *patterns;

src/utilities/kernelscan.c:113:22: note: Shadowed declaration
 static klog_pattern *patterns;

src/utilities/kernelscan.c:352:16: note: Shadow variable
 klog_pattern *patterns;
