[PATCH] tests/qtest/tpm: Remove redundant check in the tpm_test_swtpm_test()

[AlexChen <alex.chen@huawei.com>]

The 'addr' would not be NULL after checking 'succ' is valid,
and it has been dereferenced in the previous code(args = g_strdup_printf()).
So the check on 'addr' in the tpm_test_swtpm_test() is redundant. Remove it.
