Unreference pixmap's FB with EXA as well in radeon_set_pixmap_bo

Browse Source 
Not doing so resulted in DRI2 page flips not actually changing the FB
being scanned out, showing intermittent flicker of the "back" buffer
rendering.

Bugzilla: https://bugs.freedesktop.org/102643
Fixes: 55e513b978 "Use reference counting for tracking KMS framebuffer
                     lifetimes"
