Sven Schnelle 46e9c4a376 s390/stackleak: Use exrl instead of ex in __stackleak_poison() ...

[ Upstream commit a88c26bb8e ]

exrl is present in all machines currently supported, therefore prefer
it over ex. This saves one instruction and doesn't need an additional
register to hold the address of the target instruction.
