Subject: [PATCH 1/2] agpgart.h: do not include <stdlib.h> from exported header

Commit 35d0f1d54ecd ("include/uapi/linux/agpgart.h: include stdlib.h in
userspace") included <stdlib.h> to fix the unknown size_t error, but
I do not think it is the right fix.

This header already uses __kernel_size_t a few lines below.

Replace the remaining size_t, and stop including <stdlib.h>.
