net: hns3: fix output information incomplete for dumping tx queue info with debugfs

[ Upstream commit 89f6bfb071182f05d7188c255b0e7251c3806f16 ]

In function hns3_dump_tx_queue_info, The print buffer is not enough when
the tx BD number is configured to 32760. As a result several BD
information wouldn't be displayed.

So fix it by increasing the tx queue print buffer length.
