quota: disable quota check for ZVOL
The quota for ZVOLs is set to the size of the volume. When the quota
reaches the maximum, there isn't an excellent way to check if the new
writers are overwriting the data or if they are inserting a new one.
Because of that, when we reach the maximum quota, we wait till txg is
flushed. This is causing a significant fluctuation in bandwidth.
In the case of ZVOL, the quota is enforced by the volsize, so we
can omit it.
This commit adds a sysctl thats allow to control if the quota mechanism
should be enforced or not.
