OSDMonitor: check mon_max_pool_pg_num when set pool pg_num

Browse Source 
Check the mon_max_pool_pg_num when creating pools, but did not

check in the the modification. So we can create a pool and then

modify pg_num exceeds the mon_max_pool_pg_num limit.

By following these steps can verify this problem

step 1: set  mon_max_pool_pg_num = 65536

step 2: ceph osd pool create testpool 65536 65536

step 3: ceph osd pool set testpool pg_num 65537
