[PATCH v8 1/6] perf mem: Fix size tracking for mem_lvl's in perf_script__meminfo_scnprintf()

When printing memory info in perf script, the entire size of the
buffer is passed to perf_mem__lvl_scnprintf() instead of the remaining
size. Pass the remaining buffer size instead.

This issue was detected by sashiko during an internal code review.
