The __uint128_t member was only added for future convenience to the
__vector128 struct. However this is a uapi header file, 31/32 bit (aka
compat layer) is still supported, but doesn't know anything about this
type:
/usr/include/asm/types.h:27:17: error: unknown type name __uint128_t
27 | __uint128_t v;
Therefore remove it again.
Fixes: b0b7b43fcc ("s390/vx: add 64 and 128 bit members to __vector128 struct")
