Subject: [PATCH 02/23] arch: alpha: drop misleading warning on spurious IRQ

The warning in ack_bad_irq() is misleading in several ways:
* the term "vector" isn't quite correct
* the printing format isn't consistent across the archs: some print decimal,
  some hex, some hex w/o 0x prefix.
* the printed linux irq isn't meaningful in all cases - we actually would
  want it to print the hw irq.

Since all call sites already print out more detailed and correct information,
we just don't need to duplicate this in each single arch. So just drop it.
