[PATCH v1 08/10] baseband/acc: remove check on HARQ memory

[Hernan Vargas <hernan.vargas@intel.com>]

Automatically reset HARQ memory to prevent errors and simplify usage.
In a way we can assume that the HARQ output operation will always
overwrite the buffer, so we can reset this from the driver to prevent
an error being reported when application fails to do this explicitly.
