[PATCH] genirq: msi: simplify msi enable and disable

The problem.  Because the disable routines leave the msi interrupts in all
sorts of half enabled states the enable routines become impossible to
implement correctly, and almost impossible to understand.

Simplifing this allows me to simply kill the buggy reroute_msix_table, and
generally makes the code more maintainable.
