perf daemon: Fix file leak in daemon_session__control
The open() function returns -1 on error.
The 'control' and 'ack' file descriptors are both initialized with
open() and further validated with 'if' statement.
'if (!control)' would evaluate to 'true' if returned value on error were
'0' but it is actually '-1'.
Fixes: edcaa47958c7438b ("perf daemon: Add 'ping' command")
