net: hns3: fix return value check bug of rx copybreak

mainline inclusion
from mainline-v6.1-rc6
commit 29df7c69
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I65DT5
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=29df7c695ed67a8fa32bb7805bad8fe2a76c1f88

----------------------------------------------------------------------

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: 99f6b5fb ("net: hns3: use bounce buffer when rx page can not be reused")
