The flag is originally defined for "basic data partitions", but not for the ESP. We reuse it for the various partitions defined by the Discoverable Partitions Spec, but it isn't defined for the ESP, hence don't check for it. Instead, do check for GPT_FLAG_NO_BLOCK_IO_PROTOCOL, as that flag actually is defined for all partition types, and recommended to use by the UEFI spec. Fixes: #5218
