msm: ipa3: fix ipa3_reset_with_open_aggr_frame_wa() memory leak

ipa3_reset_with_open_aggr_frame_wa() expects dma memory to be freed
in a callback function that is not called in this scenario. This change
frees the memory inside the ipa3_reset_with_open_aggr_frame_wa()
after aggregation is force closed and the dma memory is not necessary
anymore.
