Adds XRA, DLFL, DLFD, RGE and ITOF packets sanity check.
Optimizes packet type table to avoid linear search during
each packet handling. Instead use packet type as index to expedite
searching. Packet type table grows to over 60 entries and each
entry uses 40B. There will be quite some memory access delay for
each packet handling without optimization.

msm_cvp_smem_put_dma_buf() releases the EVA driver's reference it uses
for DMA mappings, by decrementing the refcount of the underlying
struct file that all DMA-BUFs use for life cycle tracking. By
accident, the EVA driver held a direct reference to the underlying
file using the struct msm_cvp_smem->file variable. The EVA driver,
after releasing it's reference to the DMA-BUF, inadvertently called
fput() on the struct_cvp_smem->file variable, which leads to a double
free.
Resolve this by removing the struct msm_cvp_smmem->file variable, and
by removing the corresponding fput().
