Attn: Clear attention interrupts

Clear attention interrupts when starting the attention handler. This
code will try to clear active attention interrupts. If an attention is
active the interrupt will remain active as well. This code is
meant to address cases where attentions have been cleared but the
associated interrupt has not been cleared. This fixes the problem of
attention handler not handling attentions after an MPIPL.
