msm: camera: tfe: Process the rdi interrupts for rdi only resource

If RDI only context has two rdi resources, only for one resources
rdi only variable will set to true. So from tfe core need to process
the rdi interrupts for only one resources. This change will avoid the
rdi interrupt processing for rdi and pix use case.
