[cifs-protocol] MS-ERREF addition requested

(Resending with CC to dochelp)

Win7 build 7000 is sending NT status code 0xC00001A1 in response to
certain Byte-Range Lock operations, for example the offset = UINT64_MAX,
length = UINT64_MAX case. I totally agree with this change, but MS-ERREF
does not document 0xC00001A1, nor do any public-facing documents that I
can find. Can we get this documented?

(An example of this can be found in the smbtorture RAW-LOCK test.)
