weston sigsegv gdb backtrace

Weston segfaults in weston_view_unmap when unfullscreening client applications.
 See attached gdb backtrace.  This regression was caught with wayland-fits
efl/egl/WindowFullscreenTest, but can be reproduced manually with
weston-terminal:

1. Launch weston-terminal
2. Fullscreen the weston-terminal with <F11>
3. Unfullscreen the weston-terminal with <F11>
4. Observe segfault
