[PATCH] fbdev: Fix return error of fb_write

Fix return code of fb_write():

If at least 1 byte was transferred to the device, return number of bytes,
otherwise:

    - return -EFBIG - if file offset is past the maximum allowable offset or
      size is greater than framebuffer length
    - return -ENOSPC - if size is greater than framebuffer length - offset
