ice: fix stack leakage
commit 949375de945f7042df2b6488228a1a2b36e69f35 upstream.
In the case of an invalid virtchannel request the driver
would return uninitialized data to the VF from the PF stack
which is a bug. Fix by initializing the stack variable
earlier in the function before any return paths can be taken.
