These patches fix the bug that leads to a null-ptr-deref if
fb_videomode_to_var() fails to allocate memory. This bug is present in
do_register_framebuffer() and fb_ser_var().

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

   fbdev: Fix do_register_framebuffer to prevent null-ptr-deref in
     fb_videomode_to_var
   fbdev: Fix fb_ser_var to prevent null-ptr-deref in fb_videomode_to_var

I've added both patches to fbdev git tree (after fixing two small typos in 
commit message).

Thanks!
