[PATCH v2][next] net: atlantic: Avoid -Wflex-array-member-not-at-end warnings

["Gustavo A. R. Silva" <gustavoars@kernel.org>]

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

Remove unused flexible-array member `buf` and, with this, fix the following
warnings:
drivers/net/ethernet/aquantia/atlantic/aq_hw.h:197:36: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
drivers/net/ethernet/aquantia/atlantic/hw_atl/../aq_hw.h:197:36: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
