powerpc/eeh: Only disable/enable LSI interrupts in EEH

Browse source

The EEH code disables and enables interrupts during the
device recovery process.  This is unnecessary for MSI
and MSI-X interrupts because they are effectively disabled
by the DMA Stopped state when an EEH error occurs.  The
current code is also incorrect for MSI-X interrupts.  It
doesn't take into account that MSI-X interrupts are tracked
in a different way than LSI/MSI interrupts.  This patch
ensures only LSI interrupts are disabled/enabled.
