ktest: Add INGORE_ERRORS to ignore warnings in boot up
When testing a kernel that has warnings, ktest.pl will fail the test when it sees the warning. If you need to test the the kernel and want to ignore the errors that are produced, the option IGNORE_ERRORS has been added. When IGNORE_ERRORS is set to something other than 0, it will ignore call traces due to WARN_ON(). Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
