Subject: [PATCH 4.4 47/79] ieee802154: at86rf230: switch from BUG_ON() to WARN_ON() on problem

4.4-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 20f330452ad8814f2289a589baf65e21270879a7 ]

The check is valid but it does not warrant to crash the kernel. A
WARN_ON() is good enough here.
Found by checkpatch.
