memblock: initialize the region merge end index
GCC 13 reports that end_rgn may be used uninitialized when building the
memblock simulator with BUILD=32 and its default sanitizer flags.
Every insertion sets end_rgn, and the nr_new check prevents merging when
there were no insertions, so this is not an uninitialized read. Initialize
the index to zero to avoid the warning without disabling the diagnostic.
