pstore: Allow prz to control need for locking

commit 663deb47880f2283809669563c5a52ac7c6aef1a upstream.

In preparation of not locking at all for certain buffers depending on if
there's contention, make locking optional depending on the initialization
of the prz.

[kees: moved locking flag into prz instead of via caller arguments]
