hv:Fix unused var value on all paths

Browse Source 
MISRAC checks whether a variable is assigned a value not used in
all branches of a program. Var value which is unused on all paths
can be removed with a consequent improvement in the readability
and efficiency of the code. This patch is used to fix these
violations.
