Subject: [PATCH] Bluetooth: btintel_pcie: Fix the error handling path of btintel_pcie_probe()

Some resources freed in the remove function are not handled by the error
handling path of the probe.

Add the needed function calls.

Fixes: c2b636b3f788 ("Bluetooth: btintel_pcie: Add support for PCIe transport")

Compile tested only.
Maybe incomplete.
