Public bug reported:

[Impact]
When xen blkfront devices are unbound, removed, disconnected or suspended, if bouncing is enabled but persistent grants are not, it would leak memory.

[Fix]
Revert commit introducing the regression.

[Test case]
suspend/resume a Xen AWS instance and check for memory leaks.

[Potential regression]
AWS Xen instances can see failures on their block devices.
