Subject: net: dsa: Do not destroy invalid network devices

[ Upstream commit 382e1eea2d983cd2343482c6a638f497bb44a636 ]

dsa_slave_create() can fail, and dsa_user_port_unapply() will properly check for the network device not being NULL before attempting to destroy it. We were not setting the slave network device as NULL if dsa_slave_create() failed, so we would later on be calling dsa_slave_destroy() on a now free'd and unitialized network device, causing crashes in dsa_slave_destroy().
