security/tpm/tspi: Always measure the cache to pcr
Most of the time when INIT_BOOTBLOCK is selected, the cache should be
empty here anyway, so this is a no-op. But when it's not empty that
means the bootblock loaded some other file before it got to the TPM
init part (which is possible, for example, if hooks like
bootblock_soc_init() load something).
