While building lsk-3.10-android branch, we run into a series
of build warnings for arm64 arch:
----------
In file included from arch/arm64/kernel/kuser32.S:32:0:
arch/arm64/include/asm/unistd32.h:24:0: warning: "__NR_restart_syscall" redefined
#define __NR_restart_syscall 0

----------
This fix removes asm/unitstd32.h include to avoid duplication of
"__NR_" syscall definitions. It is based on mainline commit:
f3e5c847ec3d "arm64: Add __NR_* definitions for compat syscalls".
The corresponding change in AOSP (commit: cfc7e99e9e39, "arm64: Add..")
seem to be the early version or backport of the above mainline
commit to aosp/android-3.10. The only difference between mainline and
aosp commit is that the latter didn't have to deal with that
problematic include because it is not present in aosp/android-3.10
unlike mainline or lsk-v3.10-android tree.
