tests: tpm-emu: Remove assert on TPM2_ST_NO_SESSIONS

bios-tables-test executes SeaBIOS. Indeed FW is needed to
fetch tables from QEMU and put them into the guest RAM. Also
the FW patches cross table pointers. At some point, SeaBIOS
ends up calling the TPM2_CC_HierarchyControl command with
TPM2_ST_SESSIONS tag, most probably steming from
tpm_set_failure/tpm20_hierarchycontrol SeaBIOS call path.
This causes an assert() in the qtest tpm emulation code.

As the goal here is not to boot SeaBIOS completely but just
let it grab the ACPI tables and consolidate them, let's just
remove the assert().
