7efbe11397 s3:libsmb/clifile use correct value for MaxParameterCount for setting EAs
Windows servers will refuse trans2 requests which use excessive
request parameters. From [MS-CIFS|:
<239> Section 3.3.5.2.5: Windows NT servers fail a transaction request with
STATUS_INSUFF_SERVER_RESOURCES, if (SetupCount + MaxSetupCount +
TotalParameterCount + MaxParameterCount + TotalDataCount + MaxDataCount)
is greater than 65*1024.

When attempting to set a large list of EAs for a file, this limit can be
hit when using CLI_BUFFER_SIZE as MaxDataCount
while the TRANS2_SET_PATH_INFORMATION response has no data reply,
only parameters (section 2.2.6.7.2).

Be as minimal as possible here to allow a maximum number of EAs to
be written.

We need NT1 => LATEST in order to work against all servers which support
DCERPC over ncacn_np.

This is a mini step in using SMB2/3 in our client side by default.

This gives us a higher chance that SMB signing is supported by the
server (as it can't be turned off for SMB2 and higher).
