ha-guide: fix incorrect statement about innodb_flush_log_at_trx_commit

Browse Source 
It looks like there was a typo for the values of innodb_flush_log_at_trx_commit

Per http://galeracluster.com/documentation-webpages/configuration.html

Note Warning: While setting innodb_flush_log_at_trx_commit to a value of
0 or 2 improves performance, it also introduces certain dangers.
Operating system crashes or power outages can erase the last second of
transaction. Although normally you can recover this data from another
node, it can still be lost entirely in the event that the cluster goes
down at the same time, (for instance, in the event of a data center
power outage).
