Kill the SHMAT crap; it's _not_ a part of user-visible API (note that it
checks that we'd come there with KERNEL_DS).

It had been a one-time kludge for ibcs2 module.  Blindly copied to
architectures than never had that shite at all, not that it had survived
even on i386 past 2.2.x (2.4 analog doesn't use that thing).

Just make it fail with -EINVAL in that case.
