Subject: [PATCH perf/core v2 3/5] Revert "perf probe: Fix to fall back to
 find probe point in symbols"

This reverts commit 906451b98b67 ("perf probe: Fix to fall back to find probe point in symbols").

Since perf-probe retries with the address of given symbol
searched from map before this path, this fall back routine
doesn't need anymore.
