powerpc/pseries: Initialise nvram_pstore_info's buf_lock
nvram_pstore_info's buf_lock is not initialized before registering,
which is clearly incorrect.
It causes some strange behavior when trying to obtain the lock during
kdump process.
On a UP configuration, the console stopped for a couple of seconds, then
"lockup suspected" warning printed out, but then it continued to run.
So try lock fails, and lockup reported, but then arch_spin_lock()
passes.
