perf mem: Fix the wrong reference in parse_record_events()
A segmentation fault can be triggered when running 'perf mem record -e ldlat-loads' The commit 35b38a71c92fa033 ("perf mem: Rework command option handling") moves the OPT_CALLBACK of event from __cmd_record() to cmd_mem(). When invoking the __cmd_record(), the 'mem' has been referenced (&). So the &mem passed into the parse_record_events() is a double reference (&&) of the original struct perf_mem mem. But in the cmd_mem(), the &mem is the single reference (&) of the original struct perf_mem mem.
