crypto: testmgr - Use heap buffer for acomp test input
Christopher Covington reported a crash on aarch64 on recent Fedora kernels: kernel BUG at ./include/linux/scatterlist.h:140! Internal error: Oops - BUG: 0 [#1] PREEMPT SMP Modules linked in: CPU: 2 PID: 752 Comm: cryptomgr_test Not tainted 4.9.0-11815-ge93b1cc #162 Hardware name: linux,dummy-virt (DT) task: ffff80007c650080 task.stack: ffff800008910000 PC is at sg_init_one+0xa0/0xb8 LR is at sg_init_one+0x24/0xb8 ...

These inputs are passed as a buffer to sg_init_one which eventually blows up with BUG_ON(!virt_addr_valid(buf)). On arm64, virt_addr_valid returns false for the kernel image since virt_to_page will not return the correct page. Fix this by copying the input vectors to heap buffer before setting up the scatterlist.
