Subject: [PATCH net 2/3] net: hns3: fix return value check bug of rx copybreak

From: Jie Wang <wangjie125@...wei.com>

The refactoring of rx copybreak modifies the original return logic, which
will make this feature unavailable. So this patch fixes the return logic of
rx copybreak.

Fixes: e74a726da2c4 ("net: hns3: refactor hns3_nic_reuse_page()")
Fixes: 99f6b5fb5f63 ("net: hns3: use bounce buffer when rx page can not be reused")
