[PATCH] Dont mix Exclusive and Shared locking calls

[<owen.smith@xxxxxxxxxx>]

From: Owen Smith <owen.smith@xxxxxxxxxx>

If the lock is acquired with ExAcquireSpinLockSharedAtDpcLevel(), it
should always be released with ExReleaseSpinLockSharedFromDpcLevel()
(unless the lock is converted to an exclusive lock)
