[PATCH 1/3] libtraceevent: Fix uninitialized has_0x compiler warning

[Michael Petlan <mpetlan@redhat.com>]

Initialize has_0x in order to supress the following compiler warning:

  event-parse.c:5654:20: warning: 'has_0x' may be used uninitialized in this function [-Wmaybe-uninitialized]
   5654 |                 if (has_0x)
        |                    ^
  event-parse.c:5619:14: note: 'has_0x' was declared here
   5619 |         bool has_0x;
        |              ^~~~~~
