Daniel Vetter a76fa3540f drm/fb-helper: Add locking to sysrq handling 
We didn't take the kernel_fb_helper_lock mutex, which protects that
code. While at it, simplify the code
- inline the function (originally shared with kgdb I think)
- drop the error tracking and all the complications
- drop the pointless early out, it served nothing
