Andrea Parri (Microsoft) 0aadb6a7bb Drivers: hv: vmbus: Introduce vmbus_request_addr_match()
The function can be used to retrieve and clear/remove a transation ID
from a channel requestor, provided the memory address corresponding to
the ID equals a specified address.  The function, and its 'lockless'
variant __vmbus_request_addr_match(), will be used by hv_pci.

Refactor vmbus_request_addr() to reuse the 'newly' introduced code.

No functional change.
