clk: clocking-wizard: check return value of devm_kasprintf()
devm_kasprintf() returns a pointer to dynamically allocated memory.
Pointer could be NULL in case allocation fails. Check pointer validity.
Identified with coccinelle (kmerr.cocci script).
Fixes: 2046338dcbc6 ("ARM: mxs: Use soc bus infrastructure")
