virtio-gpu: fix memory leak in update_cursor_data_virgl

Browse source 
In update_cursor_data_virgl function, if the 'width'/ 'height'
is not equal to current cursor's width/height it will return
without free the 'data' allocated previously. This will lead
a memory leak issue. This patch fix this issue.
