IB/hfi1: Remove kobj from hfi1_devdata
The field kobj was added to hfi1_devdata structure to manage the life time
of the hfi1_devdata structure for PSM accesses:
commit e11ffbd57520 ("IB/hfi1: Do not free hfi1 cdev parent structure early")
Later another mechanism user_refcount/user_comp was introduced to provide
the same functionality:
commit acd7c8fe1493 ("IB/hfi1: Fix an Oops on pci device force remove")
This patch will remove this kobj field, as it is no longer needed.
