This issue occurs only when multiadapters are present.Hang
happens because assign_chcr_device returns u_ctx pointer of
adapter which is not yet initialized as for this adapter cxgb_up
is not been called yet.
The last_dev pointer is used to determine u_ctx pointer and it
is initialized two times in chcr_uld_add in chcr_dev_add respectively.
The fix here is don't initialize the last_dev pointer during
chcr_uld_add. Only assign to value to it when the adapter's
initialization is completed i.e in chcr_dev_add.
