Support surprise removal

Browse Source 
WHLK 1903 CHAOS tests are reporting lots of issues regarding surprise
removal misbehavior:

WDTF_PNP: INFO  : Result: TestSurpriseRemove operation timed out waiting
   for IRP_MN_REMOVE_DEVICE..
WDTF_PNP: ERROR : Result: Failed to receive IRP_MN_REMOVE_DEVICE after
   receiving IRP_MN_SURPRISE_REMOVAL. Ensure that there are no open
   handles or references to the test device (in user mode or in kernel
   mode) preventing IRP_MN_REMOVE_DEVICE from being sent. You may need
   to terminate any processes or services that may have open user mode
   handles to this device.  ( 80004005 ).
