perf: intel-tpebs: Fix incorrect usage of zfree()

[ Upstream commit 6d2dcd635204c023eb5328ad7d38b198a5558c9b ]

zfree() requires an address otherwise it frees what's in name, rather
than name itself. Pass the address of name to fix it.

This was the only incorrect occurrence in Perf found using a search.

Fixes: 8db5cabcf1b6 ("perf stat: Fork and launch 'perf record' when 'perf stat' needs to get retire latency value for a metric.")
