[PATCH v11 8/8] interconnect: sdm845: Fix build failure after cmd_db API change

[Georgi Djakov]

Recently the cmd_db_read_aux_data() function was changed to avoid using
memcpy and return a pointer instead. Update the code to the new API and
fix the build failure.

Fixes: ed3cafa79ea7 ("soc: qcom: cmd-db: Stop memcpy()ing in 
cmd_db_read_aux_data()")
