fb: handle NULL pointers in framebuffer release

Browse Source 
This function is called with a potential NULL pointer in
picolcd_init_framebuffer() and it causes a static checker warning.  This
used to handle NULL pointers when the picolcd code was written, but a
couple months later we added the "info->apertures" dereference.
