Subject[PATCH] ftrace: Don't convert function's local variable name in macro
"call" is a argument of macro, but it is also used as a local variable name of
function in macro.
We should keep this local variable name static although it haven't cause
problem now.

[ Impact: cleanup, no functionality changed ]
