Revert "msm: adsprpc: Validate sessions of process are of same pd type on same dsp."

This reverts commit 49d8960d0c08c89f26e267fcca8ac6a07e9d60c1.

Reason for revert: This change will block applications which will create
multiple sessions with different pd type. Hence need to revert the change.
Keeping 3rd party app to create multiple session intact.
