The current quota error message doesn't always print the disk name, so
it is hard to identify the "bad" disk when quota error happens.
This patch changes the standardized quota error message to print out disk name
and function name. It also uses a combination of cpp macro and inline function
to provide better type checking and to lower the text size of the message.

Quota stats is mostly writable data structure. Let's alloc percpu
bucket for each value.
NOTE: dqstats_read() function is racy against dqstats_{inc,dec}
and may return inconsistent value. But this is ok since absolute
accuracy is not required.
