tpm2: When writing state initialize s_ContextSlotMask if not set

If s_ContextSlotMask was not set since the TPM 2 was not initialized
by a call to TPM_Manufacture() or the state was not resumed, then
initialize the s_ContextSlotMask to 0xffff.

This situation can occur if a VM with an attached swtpm was started
and the VM's firmware either doesn't support TPM or didn't get to
initialize the vTPM.

The following commands recreated the issue with a SeaBIOS-only VM that
had no attached hard disk but an attached TPM 2:

virsh start BIOS-only-VM ; virsh save BIOS-only-VM save.bin ; \
 virsh restore save.bin

Error: Failed to restore domain from save.bin
error: internal error: qemu unexpectedly closed the monitor: \
