drm_fb_helper: Preserve capability to use atomic kms

Commit 5349ef3127c77075ff70b2014f17ae0fbcaaf199 (drm/fb: fix
FBIOGET/PUT_VSCREENINFO pixel clock handling) changed the logic of
when a pixclock was valid vs invalid.

The atomic kernel mode setting used by the kernel debugger relies upon
the drm_fb_helper_check_var() to always return -EINVAL.  Until a
better solution exists, this behavior will be restored.
