qemu: Avoid entering monitor with locked driver

Browse Source 
This avoids possible deadlock of the qemu driver in case a domain is
begin migrated (in Begin phase) and unrelated connection to qemu driver
is closed at the right time.

I checked all callers of qemuDomainCheckEjectableMedia() and they are
calling this function with qemu driver locked.
