Subject: libbpf: Remove redundant check in btf_fixup_datasec()
Patch-mainline: v5.18-rc1
Git-commit: 6966d4c4425b6796b1da13a6f86d09825df3d323
References: jsc#PED-1377

The check 't->size && t->size != size' is redundant because if t->size
compares unequal to 0, we will just skip straight to sorting variables.
