smb3: add indatalen that can be a non-zero value to calculation of credit charge in smb2 ioctl
Some of tests in xfstests failed with cifsd kernel server since commit e80ddeb2f70e. cifsd kernel server validates credit charge from client by calculating it base on max((InputCount + OutputCount) and (MaxInputResponse + MaxOutputResponse)) according to specification. MS-SMB2 specification describe credit charge calculation of smb2 ioctl : If Connection.SupportsMultiCredit is TRUE, the server MUST validate CreditCharge based on the maximum of (InputCount + OutputCount) and (MaxInputResponse + MaxOutputResponse), as specified in section 3.3.5.2.5. If the validation fails, it MUST fail the IOCTL request with STATUS_INVALID_PARAMETER. This patch add indatalen that can be a non-zero value to calculation of credit charge in SMB2_ioctl_init().
