[PATCH 1/7] perf inject: don't proceed if perf_session__process_event fails

[David Carrillo-Cisneros]

All paths following perf_session__process_event in __cmd_inject are
useless if __cmd_inject is to fail, some depend on a correct
session->evlist.

First commit to add code that depends on session->evlist without checking
error was commmit e558a5bd8b ("perf inject: Work with files"). It has
grown since then.

Change __cmd_inject to fail immediately after perf_session__process_event
fails.
