vmm: Re-arm the PIT callout for square wave mode
The 8254's square wave mode (mode 3) is periodic, with the same
interrupt rate as the rate generator mode (mode 2), but
vatpit_callout_handler() only re-arms the channel 0 callout for
TIMER_RATEGEN. A guest that programs mode 3 therefore receives a
single IRQ0 and no further timer interrupts.
Re-arm the callout for TIMER_SQWAVE as well, matching illumos
change 13301.
