s390: fix compat system call table

Browse Source 
commit e779498df5 upstream.

When wiring up the socket system calls the compat entries were
incorrectly set. Not all of them point to the corresponding compat
wrapper functions, which clear the upper 33 bits of user space
pointers, like it is required.
