[PULL 3/9] target/hexagon: kick vCPU when re-asserting interrupts

[Brian Cain <brian.cain@oss.qualcomm.com>]

hex_interrupt_update() used cpu_resume() to make a halted vCPU notice a
newly pending interrupt.  cpu_resume() is meant for a vCPU stopped by the
vm-state machinery: besides kicking the thread it clears cpu->stop and
cpu->stopped, and resets exception_index to -1.  Clearing the stop flags
can undo a pause requested via the monitor or by migration, and resetting
exception_index discards an exception the vCPU had already latched.

Only the kick is wanted here, so call qemu_cpu_kick() directly.
