Tools: hv: vss: Thaw the filesystem and continue if freeze call has timed out
If a FREEZE operation takes too long, the driver may time out and move on to another operation. The daemon is unaware of this and attempts to notify the driver that the FREEZE succeeded. This results in an error from the driver and the daemon leaves the filesystem in frozen state. Fix this by thawing the filesystem and continuing.
