net: hns3: add cond_resched() to hns3 ring buffer init process

[ Upstream commit 968fde83 ]

Currently hns3 ring buffer init process would hold cpu too long with big
Tx/Rx ring depth. This could cause soft lockup.

So this patch adds cond_resched() to the process. Then cpu can break to
run other tasks instead of busy looping.

Fixes: a723fb8e
