Scott Mayhew 5496b9b77d kunit: bail out early in __kunit_test_suites_init() if there are no suites to test 
Commit c72a870926 added a mutex to prevent kunit tests from running
concurrently.  Unfortunately that mutex gets locked during module load
regardless of whether the module actually has any kunit tests.  This
causes a problem for kunit tests that might need to load other kernel
modules (e.g. gss_krb5_test loading the camellia module).

So check to see if there are actually any tests to run before locking
the kunit_run_lock mutex.

Fixes: c72a870926 ("kunit: add ability to run tests after boot using debugfs")
