Jorgen Hansen 6b34aa5204 VMCI: Use set_page_dirty_lock() when unregistering guest memory 
[ Upstream commit 5a16c535409f8dcb7568e20737309e3027ae3e49 ]

When the VMCI host support releases guest memory in the case where
the VM was killed, the pinned guest pages aren't locked. Use
set_page_dirty_lock() instead of set_page_dirty().

Testing done: Killed VM while having an active VMCI based vSocket
connection and observed warning from ext4. With this fix, no
warning was observed. Ran various vSocket tests without issues.

Fixes: 06164d2b72 ("VMCI: queue pairs implementation.")
