keep the PID file locked for the lifetime of the process
The lockf() call in qemu_create_pidfile() aims at ensuring mutual
exclusion. We shouldn't close the pidfile on success (as introduced by
commit 1bbd1592), because that drops the lock as well [1]:
"File locks shall be released on first close by the locking process
of any file descriptor for the file."Coverity may complain again about the leaked file descriptor; let's
worry about that later.
v1->v2:
- add reference to 1bbd1592
- explain the intentional fd leak in the source
