m68knommu: fix syscall restart handling
Fix system call restart handling. We can call directly to the restart handler, no need to back track through trap that isn't even implemented on m68knommu. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
