Yin, Fengwei 11e67f1c4a softirq: move softirq from hv_main to interrupt context
softirq shouldn't be bounded to vcpu thread. One issue for this
is shell (based on timer) can't work if we don't start any guest.

This change also is trying best to make softirq handler running
with irq enabled.

Also update the irq disable/enabel in vmexit handler to align
with the usage in vcpu_thread.
