From: "Steven Rostedt (VMware)" <>

Fixing an issue with parsing "(REC)->" when it expected "REC->", changed
the test of "->" to read into a "token" variable instead of just
"expecting" it. This was needed to test for the ")" case. But since it is
now read into a token, that token needs to be freed. But that was missed.

Free the token.

This was found by the libtracefs "make test_mem" tests.
