Bartlomiej Zolnierkiewicz 0adcdbcb17 video: fbdev: don't print error message on framebuffer_alloc() failure 
framebuffer_alloc() can fail only on kzalloc() memory allocation
failure and since kzalloc() will print error message in such case
we can omit printing extra error message in drivers (which BTW is
what the majority of framebuffer_alloc() users is doing already).
