xtensa: fix sysmem reservation at the end of existing block
commit be6ae382dc153da51cf066c8dd523aa955f02531 upstream.
When sysmem reservation occurs exactly at the end of an existing block
that block is deleted, because it is incorrectly included in the range
of memblocks to remove. Fix that by skipping such block.
