avfilter/af_anequalizer: Fix memleak when inserting pad fails
It has been forgotten to free the name of the second outpad if attaching
the first one to the AVFilterContext fails. Fixing this is easy: Only
prepare the second outpad after (and if) the first outpad has been
successfully attached to the AVFilterContext.
