perf probe: Fix a precedence bug
The minus operator has higher precedence than ?: Add parentheses around
?: fix this.
Before this patch:
$ echo 'p:myprobe do_sys_open' > /sys/kernel/debug/tracing/kprobe_events
$ perf probe -l -k ../vmlinux
kprobes:myprobe (on do_sys_open)
After this patch:
$ echo 'p:myprobe do_sys_open' > /sys/kernel/debug/tracing/kprobe_events
$ perf probe -l -k ../vmlinux
kprobes:myprobe (on do_sys_open@linux.git/fs/open.c)
