s390/syscalls: Remove system call table pointer from thread_struct

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

With compat support gone there is only one system call table
left. Therefore remove the sys_call_table pointer from
thread_struct and use the sys_call_table directly.
