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