s390/switch_to: fix save_access_regs() / restore_access_regs()

Browse source

Fix broken contraints for both save_access_regs() and restore_access_regs().
The constraints are incorrect since they tell the compiler that the inline
assemblies only access the first element of an array of 16 elements.
Therefore the compiler could generate incorrect code.
