    net: qede: sanitize 'rc' in qede_add_tc_flower_fltr()
    
    [ Upstream commit e25714466abd9d96901b15efddf82c60a38abd86 ]
    
    Explicitly set 'rc' (return code), before jumping to the
    unlock and return path.
    
    By not having any code depend on that 'rc' remains at
    it's initial value of -EINVAL, then we can re-use 'rc' for
    the return code of function calls in subsequent patches.
    
    Only compile tested.
