net: hns3: refine tx timeout count handle
In current codes, tx_timeout_cnt is used before increased, then we can see the tx_timeout_count is still 0 from the print when tx timeout happens, e.g. "hns3 0000:7d:00.3 eth3: tx_timeout count: 0, queue id: 0, SW_NTU: 0xa6, SW_NTC: 0xa4, HW_HEAD: 0xa4, HW_TAIL: 0xa6, INT: 0x1" The tx_timeout_cnt should be updated before used.
