alloc_tag: avoid implicit padding in uapi
The implied padding causes a harmless warning when testing the uapi
headers with -Wpadded that could in theory indicate incompatibilities
or data leaks:
./usr/include/linux/alloc_tag.h:41:1: error: padding struct size to alignment boundary with 7 bytes [-Werror=padded]
The code here is fine, but it's better to make the padding explicit and
avoid the warning here.
