wifi: iwlwifi: validate payload length in iwl_pnvm_complete_fn
iwl_pnvm_complete_fn() casts pkt->data directly to
struct iwl_pnvm_init_complete_ntfy and reads the status field
without first verifying that the firmware notification payload
is large enough to contain that structure.
Add a WARN_ON_ONCE check against sizeof(*pnvm_ntf) and return
early without reading uninitialised memory if the payload is too
short.
Fixes: b3e4c0f34c17 ("iwlwifi: move PNVM implementation to common code")
