ext4: Fix ext4_quota_write cross block boundary behaviour

Browse source

We always assume what dquot update result in changes in one data block
But ext4_quota_write() function may handle cross block boundary writes
In fact if this ever happen it will result in incorrect journal
credits reservation, and later a BUG_ON.  As soon this never happen
the boundary cross loop is NOOP.  In order to make things straight
let's remove this loop and assert cross boundary condition.
