Applied patch from jira issue - OFBIZ-4528 - Out of stock products screw up the pagination during category browsing.
===================================================================
Pagination is handled in getProductCategoryAndLimitedMembers
Then the out of stock filtering is done in CategoryDetail.groovy.
Hence the pagination is screwed up. Certain pages might show less records or no records based upon data condition.

Thanks Arun for the contribution and Thanks Kiran for creating the issue.
