Subject: [PATCH] Fix for infinite loop in impd_apply_gains_and_add function

if (iEnd == iStart) is true until end line of loop,
and (drc_gain_last == shape_filter_block[g].drc_gain_last)
is also true, this make iEnd unchanged for ever
and the while loop will go into infinite iterations.
Hence added a check to break for the same.
