libpayload: Fix memalign() for fragmented alignment regions
Found a bug in the memory allocator ;-)
If the total free space in an alignment region is large enough for an
allocation but fragmented, such that there is no contiguous, sufficient
large, free space in the region, memalign() was looking at the same
region again and again in an endless loop. The advancing to the next
region was just missing.
