mtd: rawnand: meson: check return value of devm_kasprintf()

Browse source 
[ Upstream commit 5a985960a4dd041c21dbe9956958c1633d2da706 ]

devm_kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful by
checking the pointer validity.
