[PATCH 5.10] Revert "selftests/ftrace: Update synthetic event syntax errors"

[Zheng Yejian]

This reverts commit 31c2e369b5335d70e913afee3ae11e54d61afef2.

The reverted commit belongs to patchset which updated synthetic event
command parsing and testcase 'trigger-synthetic_event_syntax_errors.tc'
Link: https://lore.kernel.org/all/20210211020950.102294806@xxxxxxxxxxx/

However this testcase update was backported alone without feature
update, which makes the testcase cannot pass on stable branch.

Revert this commit to make the testcase correct.

Fixes: 31c2e369b533 ("selftests/ftrace: Update synthetic event syntax errors")
