*Describe the bug*
I have a chardev use to write screen info to spice, After multiple write and pauses, the chardev channel becomes unwriteable. And give the error "invalid argment".
the chardev xml as follow:
```xml
<channel type='spiceport'>
<source channel='org.test.raw.0'/>
<target type='virtio' name='org.test.raw.0' state='disconnected'/>
<alias name='channel16'/>
<address type='virtio-serial' controller='0' bus='0' port='17'/>
</channel>
```

*To Reproduce*
1.multiple write and pauses the chardev
2. chardev channel becomes unwriteable
3. qemu backend can't get the data
4. reboot vm and it recovery(not destroy qemu progress,reboot in vm)

*Expected behavior*
write is not error,qemu can get the write data.

*Screenshots*
vm write code:

Normal situation, we can see spice_vm_read be called.

After unwriteable, I have a code to test it, it get the error: "invalid argment"

test code:
```
#include <cstdio>
#include <cstring>
#include <thread>
#include <chrono>

#define WRITE_IO "\\\\.\\Global
org.test.raw.0"

int main(int argc, char* argv[])
{

const char* path = WRITE_IO;
// const char* path = argv[1];
printf("Opening %s ...\n", path);

FILE* fp = fopen(path, "wb");
if (!fp)

{ perror("fopen failed"); return 1; }

printf("Start writing. Press Ctrl+C to stop.\n");

int counter = 0;
while (true)
{
char buf[4096 + 5];
int len = snprintf(buf, sizeof(buf), "Hello %d\n", counter++);

size_t written = fwrite(buf, 1, 4096, fp);
fflush(fp);

if (written != (size_t)4096)

{ printf("Write error, written=%zu errno=%d desc[%s]\n", written, errno, strerror(errno)); continue; }

printf("Written: %s", buf);
std::this_thread::sleep_for(std::chrono::milliseconds(10));
}

fclose(fp);
return 0;
}
