Subject: nvme-auth: fix an error code in nvme_auth_process_dhchap_challenge()
Patch-mainline: v6.3-rc1
Git-commit: 51d24f701f453c18cb5f4596d8bbe8034e5d3fb4
References: bsc#1202633

This function was transitioned from returning NVMe status codes to
returning traditional kernel error codes.  However, this particular
return now accidentally returns positive error codes like ENOMEM instead
of negative -ENOMEM.

Fixes: b0ef1b11d390 ("nvme-auth: don't use NVMe status codes")
