For sure coalescing parameters must not persist on a vq reset in the device.
VQ reset operation destroys or disables the VQ.
Device should not have any obligation to maintain some parameter on the disabled/destroyed object.

User likely disabled the VQ because user may want to have a fresh start for this VQ for same or different use.
And hence, reconfiguring the new addresses, new vq size, new vq notifications parameters..
