s390: remove runtime instrumentation interrupts
The external interrupts for runtime instrumentation buffer-full and runtime instrumentation halted are unused and have no current user. Remove the support and ignore the second parameter of the s390_runtime_instr system call from now on. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
