mtd: powernv: Add check devm_kasprintf() returned value

Browse source 
[ Upstream commit 395999829880a106bb95f0ce34e6e4c2b43c6a5d ]

devm_kasprintf() can return a NULL pointer on failure but this
returned value is not checked.

Fixes: acfe63ec1c59 ("mtd: Convert to using %pOFn instead of device_node.name")
