brcmfmac: Replace zero-length array with flexible array member
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use "flexible array members"[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
Also, make use of the struct_size() helper in devm_kzalloc().
