perf inject: Don't proceed if perf_session__process_event() fails
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.
