net: ll_temac: check the return value of devm_kmalloc()
commit b352c3465bb808ab700d03f5bac2f7a6f37c5350 upstream.
devm_kmalloc() returns a pointer to allocated memory on success, NULL
on failure. While lp->indirect_lock is allocated by devm_kmalloc()
without proper check. It is better to check the value of it to
prevent potential wrong memory access.
