paging: Optimize retrieving number of request per paging group
This patch caches the counts of initial paging requests for each paging
group. This count is needed to estimate T3113 when a new incoming paging
request is received and it has to be inserted into the queue.
With this there's no need to traverse the whole initial_req_list every
time a new incoming paging request is receiving, potentially saving lots
of iteration and hence lots of CPU when the queue is long.
