[PATCH ndctl 1/3] cxl/event_trace: fix a resource leak in cxl_event_to_json()

[Vishal Verma <vishal.l.verma@intel.com>]

Static analysis reports that a 'return -ENOMEM' in the above function
bypasses the error unwinding and leaks 'jevent'.

Fix the error handling to use the right goto sequence before returning.
