From: Mihai Carabas <mihai.carabas@oracle.com>

[ Upstream commit a99009bc4f2f0b46e6c553704fda0b67e04395f5 ]

Add again dev_set_drvdata(), but this time in devm_pvpanic_probe(), in order
for dev_get_drvdata() to not return NULL.

Fixes: 394febc9d0a6 ("misc/pvpanic: Make 'pvpanic_probe()' resource managed")
