[libvirt] [PATCH 2/3] virSysinfoParseX86BaseBoard: Free memory upfront if no board detected
If no board was detected then VIR_REALLOC_N() done at the end of
the function will actually free the memory (because nborads ==
0), but @boards will be set to a non-NULL pointer. This makes it
unnecessary harder for a caller to see if any board was detected.
