Remove fail for syslog rate limit test

[maunnikr-cisco]

Description of PR

Summary:
Fixes # (issue)
the TC syslog/test_syslog_rate_limit.py was made to XPASS - i.e. it was set such that it is not expected to pass owing to this issue - #11181 - which has now been closed. Therefore, we no longer need to make this a fail test case, and can continue to expect it to pass.

Approach

What is the motivation for this PR?

#11181 is resolved, and the below TC is no longer expected to fail, therefore need not be marked as an fail TC.

How did you do it?

How did you verify/test it?

Initiated runs on local testbeds with the latest image.
syslog_rate_limit.log

Any platform specific information?

Supported testbed topology if it's a new test case?
