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().

Persistent buffer unmap is different than frame buffer. It's
expected to be released at the end of session instead of at
frame boundary. Remove the warning of "unexpected unmapping".

In DSP use case, if application failed to free dma buffer before
session end. Kernel driver will free all dma buffers belong to the
dsp session. During this process, same dma buffer was freed twice.
This change is to fix the problem.
