Fix static variable data race access [17163]

[jparisu]

Signed-off-by: jparisu javierparis@eprosima.com

There is a static (global) variable that is supposed to contain default values, but it does not.
This variable is sent to multiple functions by default by reference, where it is modified (it is not default anymore) without guards (TSAN issues).
