Clarify journal size based on filestore max sync

The docs had the recommended journal size based on the option
"filestore min sync interval" when it should have been
"filestore max sync interval".

While in there, fix a couple of typos -- multiple when it should
be multiply, and a missing word.  Change "Should at least twice"
to "Should be at least twice..."

 Ceph's default ``osd journal size`` is 0, so you will need to set this in your 
 ``ceph.conf`` file. A journal size should find the product of the ``filestore
-min sync interval`` and the expected throughput, and multiple the product by 
+max sync interval`` and the expected throughput, and multiply the product by 
 two (2)::  
          
-       osd journal size = {2 * (expected throughput * filestore min sync interval)}
+       osd journal size = {2 * (expected throughput * filestore max sync interval)}
 
 The expected throughput number should include the expected disk throughput
 (i.e., sustained data transfer rate), and network throughput. For example,
