Skip patches generation for structs with a single field.
Changing a zero-length array to a flexible array member in a struct
with no named members breaks the compilation. However, reporting
such cases is still valuable, e.g. commit 637464c59e0b
("ACPI: NFIT: Fix flexible_array.cocci warnings").

One-element and zero-length arrays are deprecated [1]. Kernel
code should always use "flexible array members" instead, except
for existing uapi definitions.
The script warns about one-element and zero-length arrays in structs.

one-element arrays")
