MINOR: vars: Delay variable content freeing in var_set function

When calling var_set on a variable of type string (SMP_T_STR, SMP_T_BIN
or SMP_T_METH), the contents of the variable were freed directly. When
adding conditions to set-var calls we might have cases in which the
contents of an existing variable should be kept unchanged so the freeing
of the internal buffers is delayed in the var_set function (so that we
can bypass it later).
