error on run qemu-system-aarch64 -icount shift=1,align=off,sleep=on -smp 2
Description of problem:
This issue happen with the most recent version. 
* Compile parameters:
```
./configure --target-list=aarch64-softmmu  --prefix=pwd/release  --disable-werror --enable-lto --enable-capstone --enable-system --enable-fdt --disable-xen --disable-kvm --enable-plugins
```
* run：
```
qemu-system-aarch64 -nographic -machine virt -cpu cortex-a57 -icount shift=1,align=off,sleep=on -smp 2 -vnc :2 -m 4080 -kernel /home/yuzy/mywork/linux/linux-5.15.30/arch/arm64/boot/Image.gz -initrd /home/yuzy/mywork/build/rootfs.cpio.gz
```
* error occurred：
```
**
ERROR:../accel/tcg/tcg-accel-ops.c:79:tcg_handle_interrupt: assertion failed: (qemu_mutex_iothread_locked())
Aborted (core dumped)
```
Steps to reproduce:
1. run qemu-system-aarch64 -machine virt -cpu cortex-a57 -icount shift=1,align=off,sleep=on -smp 2 -m 4080 -kernel Image.gz -initrd rootfs.cpio.gz 
2. it will assertion failed: (qemu_mutex_iothread_locked())
Additional information:
The following two situations are good：
```
qemu-system-aarch64 -machine virt -cpu cortex-a57 -icount shift=1,align=off,sleep=on -smp 1 -m 4080 -kernel Image.gz -initrd rootfs.cpio.gz
```
```
qemu-system-aarch64 -machine virt -cpu cortex-a57 -smp 2 -m 4080 -kernel Image.gz -initrd rootfs.cpio.gz
```
I assume the issues are: gic
