-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Change the type of the middle struct member currently causing
trouble from `struct ethtool_link_settings` to `struct
ethtool_link_settings_hdr`.
Additionally, update the type of some variables in various functions
that don't access the flexible-array member, changing them to the
newly created `struct ethtool_link_settings_hdr`.
Fix 3338 of the following -Wflex-array-member-not-at-end warnings:
include/linux/ethtool.h:214:38: warning: structure containing a flexible array
member is not at the end of another structure [-Wflex-array-member-not-at-end]
