sys/vfs/hammer2: Fix double count of hammer2_iod_file_{read,write}
These two are double counting data chain read / write.
* The strategy read lookups a data chain and ends up calling
hammer2_adjreadcounter() from hammer2_chain_load_data().
* The strategy write ends up calling hammer2_adjwritecounter()
when a dirty dio is putblk'd.
Also note that hammer2_iod_xxx counters are for total I/O bytes
according to functions above, not number of times called.
