shim/tpm: fix trigger failure caused by NULL arguments

Certain AMI BIOS (Intel NUC5i3MYBE BIOS version 0037) may make the strict
check on the last 3 arguments passed to get_event_log() and don't expect
NULL pointers are passed. In order to work around this failure
(EFI_INVALID_PARAMETER), pass them even though we really don't use it.
