Subject: [PATCH] mempool: fix search of maximum contiguous pages

[ upstream commit 1e975578bc30a84547b62bd682b03f8f08bf3a38 ]

paddr[i] + pg_sz always points to the start physical address of the
2nd page after pddr[i], so only up to 2 pages can be combinded to
be used. With this revision, more than 2 pages can be used.

Fixes: 84121f197187 ("mempool: store memory chunks in a list")
