perf probe: Add error checks to offline probe post-processing

commit 3e96dac7c956089d3f23aca98c4dfca57b6aaf8a upstream.

Add error check codes on post processing and improve it for offline
probe events as:

 - post processing fails if no matched symbol found in map(-ENOENT)
   or strdup() failed(-ENOMEM).

 - Even if the symbol name is the same, it updates symbol address
   and offset.
