tpm_emulator: Have swtpm relock storage upon migration fall-back
Swtpm may release the lock once the last one of its state blobs has been migrated out. In case of VM migration failure QEMU now needs to notify swtpm that it should again take the lock, which it can otherwise only do once it has received the first TPM command from the VM.
Only try to send the lock command if swtpm supports it. It will not have released the lock (and support shared storage setups) if it doesn't support the locking command since the functionality of releasing the lock upon state blob reception and the lock command were added to swtpm 'together'.
If QEMU sends the lock command and the storage has already been locked no error is reported.
If swtpm does not receive the lock command (from older version of QEMU), it will lock the storage once the first TPM command has been received. So sending the lock command is an optimization.

qdev: Rename qdev_get_prop_ptr() to object_field_prop_ptr()
The function will be moved to common QOM code, as it is not specific to TYPE_DEVICE anymore.
