[PATCH V3 3/3] nvmet-auth: use correct type for status variable

[Chaitanya Kulkarni]

The dhchap_step member of structure nvmet_sq holds the following values:

        NVME_AUTH_DHCHAP_FAILURE_FAILED                 = 0x01,
        NVME_AUTH_DHCHAP_FAILURE_NOT_USABLE             = 0x02,
        NVME_AUTH_DHCHAP_FAILURE_CONCAT_MISMATCH        = 0x03,
        NVME_AUTH_DHCHAP_FAILURE_HASH_UNUSABLE          = 0x04,
        NVME_AUTH_DHCHAP_FAILURE_DHGROUP_UNUSABLE       = 0x05,
        NVME_AUTH_DHCHAP_FAILURE_INCORRECT_PAYLOAD      = 0x06,
        NVME_AUTH_DHCHAP_FAILURE_INCORRECT_MESSAGE      = 0x07,

These values can never be negative, hence change int type of
dhchap_step to u16 in the nvmet_sq struct.
