ksmbd: return buffer too small for short security queries
SMB2 QUERY_INFO security requests with an output buffer too small for
the self-relative security descriptor header can fall through descriptor
construction and be reported as STATUS_INVALID_INFO_CLASS.
After validating the file handle, reject buffers shorter than struct
smb_ntsd with STATUS_BUFFER_TOO_SMALL before building the descriptor.
This fixes smb2.getinfo.qsec_buffercheck.
