Subject: net: hns3: fix the bug when map buffer fail
From: Lipeng <lipeng321@huawei.com>
[ Upstream commit 564883bb4dc1a4f3cba6344e77743175694b0761 ]
If one buffer had been recieved to stack, driver will alloc a new buffer,
map the buffer to device and replace the old buffer. When map fail, should
only free the new alloced buffer, but not free all buffers in the ring.
