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().
