[PATCH] arm64: ni_syscall should be similar to other archs

[per.hallsmark at windriver.com]

From: Per Hallsmark <per.hallsmark at windriver.com>

Today arm64 have it's own variant when a userspace app is doing a
non-implemented syscall in that it dumps on console process name,
registers and such. This makes a different behaviour on arm64 than
on all other archs.

This patch propose to get inline with other archs.

If we want to have a note on console, syslog or so when doing a
nonimplemented syscall, it would be better to add a variable
show_nonimplemented_syscalls and sense on it in the generic
kernel/sys_ni.c::sys_ni_syscall() which could dump info (and then
it would be generic for all archs). But that is another discussion
alltogether, lets first synchronize the archs to behave similar.
