net: hns3: add cond_resched() to hns3 ring buffer init process
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: a723fb8efe29 ("net: hns3: refine for set ring parameters")
