pstore: don't OOPS when there are no ftrace zones
We'll OOPS in ramoops_get_next_prz() if the platform didn't ask for any
ftrace zones (i.e., cxt->fprzs will be NULL). Let's just skip this
entire FTRACE section if there's no 'fprzs'.
Regression seen on a coreboot/depthcharge-based Chromebook.
Fixes: 2fbea82bbb89 ("pstore: Merge per-CPU ftrace records into one")
