This is the following patch after removing pending_pre_work, it make sure
all io emulation is done on its own cpu.
For hv emulated request, it follows the steps:
hv_emulate_pio->emulate_pio_complete
hv_emulate_mmio->emulate_mmio_complete
For dm emulated request, it follows the steps:
acrn_insert_request->dm_emulate_io_complete
while in acrn_insert_request, it could trigger scheduling out then resume by
hcall_notify_ioreq_finish, or busy wait for ioreq completion if polling mode
is enabled.

Under sharing mode, VM0 is identical with SOS VM. But the coupling of
SOS VM and VM 0 is not friendly for partition mode.
This patch is a pure term change of vm0 to sos VM, it does not change
any code logic or senmantic.
