perf probe: Fix to ensure function declared file
perf probe: Fix to ensure function declared file

Fix to ensure function declared file matches given file name. This fixes
a potential bug.

As I've commented on Lin Ming's fastpath enhancement, decl_file should
be checked on each probe point if user gives a probe point as func@file.
