msm: mhi_dev: Adding check in open channel API 



Adding check for mhi_ctx and mhi_ctx->pdev in mhi_dev_open_channel API
which is called by the clients. This prevents the device crash when
mhi_dev_open_channel is called in PCIe RC configuration or when it is
called when mhi_ctx is not created yet.
