Richard Fitzgerald 1557e89d3a kunit: debugfs: Handle errors from alloc_string_stream()
In kunit_debugfs_create_suite() give up and skip creating the debugfs
file if any of the alloc_string_stream() calls return an error or NULL.
Only put a value in the log pointer of kunit_suite and kunit_test if it
is a valid pointer to a log.

This prevents the potential invalid dereference reported by smatch:

 lib/kunit/debugfs.c:115 kunit_debugfs_create_suite() error: 'suite->log'
	dereferencing possible ERR_PTR()
 lib/kunit/debugfs.c:119 kunit_debugfs_create_suite() error: 'test_case->log'
	dereferencing possible ERR_PTR()
