ASoC: SOF: ipc3: Check for upper size limit for the received message
[ Upstream commit 989a3e4479177d0f4afab8be1960731bc0ffbbd0 ]
The sof_ipc3_rx_msg() checks for minimum size of a new rx message but it is
missing the check for upper limit.
Corrupted or compromised firmware might be able to take advantage of this
to cause out of bounds reads outside of the message area.
