*: Use fprintf between qemu_log_trylock/unlock
Inside qemu_log, we perform qemu_log_trylock/unlock, which need
not be done if we have already performed the lock beforehand.
Always check the result of qemu_log_trylock -- only checking
qemu_loglevel_mask races with the acquisition of the lock on
the logfile.
