msm: camera2: cpp: Fix out-of-bounds frame or command buffer access

When user application provides invalid (out of range) stripe size and
stripe indices, while submitting  requests for the stripe based image
processing by the CPP kernel driver, the driver could  perform out of
bounds access of the internal buffers.

This fix ensures that stripe size and indices of frame/command buffer
are properly validated during the configuration and before processing
such requests through the CPP hardware block.
