MFC: Split the intr_table_lock into an sx lock used for most things, and a
spin lock to protect intrcnt_index.  Originally I had this as a spin lock
so interrupt code could use it to lookup sources.  However, we don't
actually do that because it would add a lot of overhead to interrupts,
and if we ever do support removing interrupt sources, we can use other
means to safely do so w/o locking in the interrupt handling code.

This fixes a LOR in the most recent MSI MFC and was a part of the original
commit to HEAD that included the changes in the most recent MSI MFC.
