wifi: iwlwifi: mvm: d3: Avoid -Wflex-array-member-not-at-end warnings

Browse source

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

Use the `DEFINE_RAW_FLEX()` helper for on-stack definitions of
a flexible structure where the size of the flexible-array member
is known at compile-time, and refactor the rest of the code,
accordingly.

So, with these changes, fix the following warnings:

drivers/net/wireless/intel/iwlwifi/mvm/d3.c:124:52: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
drivers/net/wireless/intel/iwlwifi/mvm/d3.c:2067:51: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
drivers/net/wireless/intel/iwlwifi/mvm/d3.c:2162:43: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
drivers/net/wireless/intel/iwlwifi/mvm/d3.c:2225:43: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
