tracing/uprobes: Fix the usage of uprobe_buffer_enable() in probe_event_enable()
The usage of uprobe_buffer_enable() added by dcad1a20 is very wrong,
1. uprobe_buffer_enable() and uprobe_buffer_disable() are not balanced,
_enable() should be called only if !enabled.
2. If uprobe_buffer_enable() fails probe_event_enable() should clear
tp.flags and free event_file_link.
3. If uprobe_register() fails it should do uprobe_buffer_disable().
