perf daemon: Fix file leak in daemon_session__control
[ Upstream commit 09541603462c399c7408d50295db99b4b8042eaa ]
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")
