ksmbd: validate file ids for query network interface info

FSCTL_QUERY_NETWORK_INTERFACE_INFO is not tied to an open file handle.
Clients send SMB2_NO_FID for both file id fields when issuing this
request.

Reject requests that provide any other file id before checking the
output buffer size. This returns STATUS_INVALID_PARAMETER for invalid
file ids instead of treating the request as valid or reporting
STATUS_BUFFER_TOO_SMALL for a small output buffer.
