xen: arm: Allow traps from 32 bit userspace on 64 bit hypervisors again

This removes the unconditional #undef injected in response to such
traps which was added by the fixes to CVE-2014-5147 / XSA-102 in
c0020e099702 "xen: arm: Handle traps from 32-bit userspace on 64-bit
kernel as undef", we now handle such traps correctly.
