[ Upstream commit b9bd25f47eb79c9eb275e3d9ac3983dc88577dd4 ]
The mailbox receive path allocates coherent DMA memory with dma_alloc_coherent(), but frees it with dmam_free_coherent(). This is incorrect since dmam_free_coherent() is only valid for buffers allocated with dmam_alloc_coherent().
Fix the mismatch by using dma_free_coherent() instead of dmam_free_coherent
