wifi: mwl8k: Use static_assert() to check struct sizes

Browse source

Commit 5c4250092f ("wifi: mwl8k: Avoid -Wflex-array-member-not-at-end
warnings") introduced tagged `struct mwl8k_cmd_pkt_hdr`. We want to
ensure that when new members need to be added to the flexible structure,
they are always included within this tagged struct.

We use `static_assert()` to ensure that the memory layout for both
the flexible structure and the tagged struct is the same after any
changes.
