accel/rocket: fix unwinding in error path in rocket_core_init

When rocket_job_init() is called, iommu_group_get() has already been
called, therefore we should call iommu_group_put() and make the
iommu_group pointer NULL. This aligns with what's done in
rocket_core_fini().

If pm_runtime_resume_and_get() somehow fails, not only should
rocket_job_fini() be called but we should also unwind everything done
before that, that is, disable PM, put the iommu_group, NULLify it and
then call rocket_job_fini(). This is exactly what's done in
rocket_core_fini() so let's call that function instead of duplicating
the code.
