ext4: quota macros cleanup
(cherry picked from commit 5aca07eb7d8f14d90c740834d15ca15277f4820c)
Currently all quota block reservation macros contains hard-coded "2"
aka MAXQUOTAS value. This is no good because in some places it is not
obvious to understand what does this digit represent. Let's introduce
new macro with self descriptive name.
