perf session: Return error code for perf_session__new() function on failure
This patch is to return error code of perf_new_session function on
failure instead of NULL.
Test Results:
Before Fix:
$ perf c2c report -input
failed to open nput: No such file or directory
$ echo $?
0
$
After Fix:
$ perf c2c report -input
failed to open nput: No such file or directory
$ echo $?
254
$
Committer notes:
Fix 'perf tests topology' case, where we use that TEST_ASSERT_VAL(...,
session), i.e. we need to pass zero in case of failure, which was the
case before when NULL was returned by perf_session__new() for failure,
but now we need to negate the result of IS_ERR(session) to respect that
TEST_ASSERT_VAL) expectation of zero meaning failure.
