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().
Fixes: e80ddeb2f70e ("smb3: fix incorrect number of credits when ioctl
MaxOutputResponse > 64K")
