integration tests: do not adjust log level in the test script

We passes log level through kernel command line. It is not necessary to
set to debug level at the beginning, and set to info at the end.
This is important when a test has several subtests. If a subtest sets
log level to info at the end, then subsequent tests may not generate any
useful logs.
