kernel_patch_verify: partial hack to ignore fail due to line change

Change in line results in delta such as:
-Warning(drivers/clk/clk.c:1802): No description found for parameter 'dev'
-Warning(drivers/clk/clk.c:1802): No description found for parameter 'hw'
-Warning(drivers/clk/clk.c:1968): No description found for parameter 'dev'
+Warning(drivers/clk/clk.c:1870): No description found for parameter 'dev'
+Warning(drivers/clk/clk.c:1870): No description found for parameter 'hw'
+Warning(drivers/clk/clk.c:2036): No description found for parameter 'dev'

This at the best irritating. instead, drop the line information and
store just the warnings.. in case new warnings are introduced, crib.

Run in parallel some of the generic tests each of which needs
sequential make operation.
