This patch set aimed to get rid of most annoying locks.
In case of journalled quota it is dq_iomutex and i_mutex.
Patches are simple and clean. Patches make difference
between nojournaled/journaled quota modes less significant.
And allow us to switch to default journalled quota without
performance penalty.

There are many other optimizations possible, but they are 
more intrusive and require wide discussions.
