[PATCH] qemu: Don't pass mode when opening domain log file for reading

In qemuDomainLogContextNew() the domain log file is opened. Twice, the first time for writing, and the second time for reading (if required by caller). When opening the log file for reading a mode is provided. This doesn't do much harm, but is unnecessary. Drop the mode.
