tpm: tpm_crb: Add the missed acpi_put_table() to fix memory leak

commit 37e90c374dd11cf4919c51e847c6d6ced0abc555 upstream.

In crb_acpi_add(), we get the TPM2 table to retrieve information
like start method, and then assign them to the priv data, so the
TPM2 table is not used after the init, should be freed, call
acpi_put_table() to fix the memory leak.
