target: remove some unused stats

This patchset removes a couple of unused error stat counters and a redundant cumulative counter.
I've tagged this patchset RFC, as it may be considered a kernel<->user (configfs) API change.

Cheers, David

Ping, any thoughts on this patchset?

I think these stats were supposed to match the iSCSI MIB definitions. It was not clear why we didn't just fix them so they report the correct values?

Hi Mike

I finally got a chance to look through rfc#4544. It does indeed look like these counters correspond to:
IscsiInstanceSsnErrorStatsEntry ::= SEQUENCE {

    iscsiInstSsnDigestErrors       Counter32,
    iscsiInstSsnCxnTimeoutErrors   Counter32,
    iscsiInstSsnFormatErrors       Counter32

}

There doesn't appear to be anything stopping us from plumbing them into the corresponding error paths, so I'll withdraw this patchset.

Cheers, David
