Add missing page rounding of a page_entry
This one place in ggc forgot to round page_entry->bytes to the
next page boundary, which lead to all the heuristics in freeing to
check for continuous memory failing. Round here too, like all other
allocators already do. The memory consumed should be the same
for MMAP because the kernel would round anyways. It may slightly
increase memory usage when malloc groups are used.
This will also increase the hitrate on the free page list
slightly.
