    smb: fix wrong exported smb2 object due to hash collision
    
    While SMB1 FIDs are 16-bit, those used in SMB2 are a GUID of 128-bit
    which are compressed down to 32-bit using g_str_hash. To reduce
    collision probability which could associate wrong file data with an
    Exported Object entry, do not truncate this hash value to 16 bits.
