Frederic Weisbecker 34aacb2920 procfs: Use generic_file_llseek in /proc/kcore ...

/proc/kcore has no llseek and then falls down to use default_llseek.
This is racy against read_kcore() that directly manipulates fpos
but it doesn't hold the bkl there so using it in llseek doesn't
protect anything.

Let's use generic_file_llseek() instead.
