efi: initialize efi.runtime_version to make query_variable_info/update_capsule workable
A value of efi.runtime_version is checked before calling update_capsule()/query_variable_info() as follows. But it isn't initialized anywhere. <snip> static efi_status_t virt_efi_query_variable_info(u32 attr, u64 *storage_space, u64 *remaining_space, u64 *max_variable_size) { if (efi.runtime_version < EFI_2_00_SYSTEM_TABLE_REVISION) return EFI_UNSUPPORTED; <snip> This patch initializes a value of efi.runtime_version at boot time.
