tests/qtest/tpm-tests: Remove unnecessary NULL checks

Coverity points out that in tpm_test_swtpm_migration_test() we
assume that src_tpm_addr and dst_tpm_addr are non-NULL (we
pass them to tpm_util_migration_start_qemu() which will
unconditionally dereference them) but then later explicitly
check them for NULL. Remove the pointless checks.

Fixes: Coverity CID 1432367, 1432359
