Subject: [PATCH v2 3/3] arm64: is_compat_task is defined both in asm/compat.h and linux/compat.h

kernel/seccomp.c includes linux/compat.h and, indicrectly, asm/compat.h
via asm/syscall.h. Due to the duplicated definitions of is_compat_task,
compiling this file will fail in the case of !CONFIG_COMPAT.
So this patch
1) removes is_compat_task() definition from asm/compat.h
2) replaces asm/compat.h to linux/compat.h in kernel/*.c
