Liu Xiaodong 53429c7f44 thread: distinguish intr enabled and set
As a start of combining interrupt ability into poller,
it aims to get spdk_thread & spdk_poller runnable between
poll mode and interrupt mode with dynamic switching.

spdk_interrupt_mode_is_enabled() indicate whether interrupt
mode is enabled and dynamic switching is permitted. So
spdk_interrupt_mode_is_enabled==true leads to set up
interrupt mode related resources;
in_interrupt flag indicates whether one spdk_thread now
is running in intr mode.
It is possible that spdk_interrupt_mode_is_enabled==true
but in_interrupt==false. this means spdk_thread & spdk_poller
switched to poll mode from interrupt mode due to heavy
workload coming.

To align with spdk_reactor, use "in_interrupt" to
indicate whether one spdk_thread now runs in intr.
