ksmbd: fix partial normalized name responses

Browse source

Windows may request FILE_NORMALIZED_NAME_INFORMATION with an output
buffer that only fits the fixed portion of the variable-length response.
Treat the fixed portion as FILE_NORMALIZED_NAME_INFORMATION_SIZE so ksmbd
returns STATUS_BUFFER_OVERFLOW instead of STATUS_INFO_LENGTH_MISMATCH.

This avoids rejecting valid partial normalized-name responses.
