log stray interrupts only if bootverbose is YES

[Matthew Dillon]

:Hi all,
:
:Following patch enables stray interrupts logging only if bootverbose is YES
:http://leaf.dragonflybsd.org/~sephe/kern_intr.c.diff
:
:My new laptop does not have ppc0, but interrupt 7 keeps coming
:intermittently.  Though its rate is extremely low (<< 1/sec), the
:logging is very annoying.
:
:OK to commit?

:Best Regards,

    That kinda kills the point of the logging.  The stray interrupt reporting
    stops when it hits 100.  Maybe make that a sysctl-configurable value
    instead of outright disabling the reporting.
