Hajime Hoshi 7b77164710 restorable: Ignore the error when restoring failed due to being not ready
(driver.Graphics).BeginFrame tries to restore the images, but
the context might be lost at that time yet. If the attempt to
restore the context because the driver is not ready, return
silently.

Fixes #1133
