genirq: Call bus_lock/unlock functions in setup_irq()

irq_chips that supply .irq_bus_lock/.irq_bus_sync_unlock functions,
expect that the other chip methods will be called inside of calls to
the pair.  If this expectation is not met, things tend to not work.

Make setup_irq() call chip_bus_lock()/chip_bus_sync_unlock() too.

For the vast majority of irq_chips, this will be a NOP as most don't
have these bus lock functions.

[ tglx: No we don't want to call that in __setup_irq(). Way too many
   error exit pathes. ]
