Subject: [PATCH AUTOSEL 4.14 02/33] mac80211_hwsim: fix incorrect dev_alloc_name failure goto

From: Michael Vassernis <michael.vassernis@...demg.com>

[ Upstream commit 313c3fe9c2348e7147eca38bb446f295b45403a0 ]

If dev_alloc_name fails, hwsim_mon's memory allocated in alloc_netdev
needs to be freed.
Change goto command in dev_alloc_name failure to out_free_mon in
order to perform free_netdev.
