efi: Initialize all configuration table addresses to EFI_INVALID_TABLE_ADDR

The addresses of the MOK variable table, the confidential computing
secret area and the unaccepted memory table in struct efi are only
initialized to EFI_INVALID_TABLE_ADDR if support for the respective
table is enabled, and are left at 0 otherwise. This is harmless for
the existing users, which are compiled out in that case, but code that
consumes the table addresses in struct efi generically, such as a kexec
loader that passes the configuration tables on to the incoming kernel,
would mistake 0 for a valid table address.

So initialize all of them unconditionally: efi_config_parse_tables()
only assigns them if support for the table is enabled, and so they
remain EFI_INVALID_TABLE_ADDR otherwise.
