hwc: virtual display: Use outbuf handle width to configure xres

Use outbuf handle width to configure display xres, since that would
have the necessary alignment. The outbuf is guaranteed to be valid
by the framework during hwc_prepare.
We use the framebuffer layer's display frame to obtain the actual
width.
For example, the actual width could be 720 but the aligned width
would be 736.
