qemu-ga: for w32, fix leaked handle ov.hEvent in ga_channel_write()

Browse source 
In the function ga_channel_write(), the handle ov.hEvent is created
by the call to CreateEvent(). However, the handle is not closed
prior to the function return.

This patch closes the handle before the return of the function.

Kudos to Paolo Bonzini for spotting this bug.
