Subject: [PATCH 4.14 027/218] rtlwifi: Use pr_warn instead of WARN_ONCE

From: Dongliang Mu <mudongliangabcd@...il.com>

[ Upstream commit ad732da434a2936128769216eddaece3b1af4588 ]

This memory allocation failure can be triggered by fault injection or
high pressure testing, resulting a WARN.

Fix this by replacing WARN with pr_warn.
