Fix: do not use diagnostic pragma when GCC version is lower than 4.6.0

Officially the diagnostic pragma are supported starting in 4.6. [1]
But they were present before 4.6 with limitation which we cannot
honour easily.

Fix: lttng-tracepoint module notifier should return NOTIFY_OK

Module notifiers should return NOTIFY_OK on success rather than the
value 0. The return value 0 does not seem to have any ill side-effects
in the notifier chain caller, but it is preferable to respect the API
requirements in case this changes in the future.

Notifiers can encapsulate a negative errno value with
notifier_from_errno(), but this is not needed by the LTTng tracepoint
notifier.

The approach taken in this notifier is to just print a console warning
on error, because tracing failure should not prevent loading a module.
So we definitely do not want to stop notifier iteration. Returning
an error without stopping iteration is not really that useful, because
only the return value of the last callback is returned to notifier chain
caller.

lttng-modules v0.19-stable: setup_trace_write: Fix recursive locking

lttng-modules: ltt_trace_destroy calls ltt_lock_traces internally so
this non-recursive mutex must be first unlocked when executing error
handling code.
