[PATCH v1 1/1] scsi: lpfc: Do not abuse UUID APIs

Andy Shevchenko
2023-08-07T09:56:21Z

The lpfc_vmid_host_uuid is not defined as uuid_t and its usage is not
the same as for uuid_t operations (like exporting or importing).
Hence replace call to uuid_is_null() by respective memchr_inv() without
abusing casting.
