[PATCH 6/7] vboxDomainScreenshot: Don't pass uninitialized 'screenData' to VIR_FREE

[Peter Krempa]

If one of the early checks to get screen resolution fails 'screenData'
would be passed to VIR_FREE uninitialized. Unfortunately the compiler
isn't able to detect this when VIR_FREE is implemented using
g_clear_pointer.
