After all the recent structural changes this is now straightfoward, hoist the hw_destroy_rwsem up out of rdma_destroy_explicit and wrap it around the uobject write lock as well as the destroy. This is necessary as obtaining a write lock concurrently with uverbs_destroy_ufile_hw() will cause malfunction. After this change none of the destroy callbacks require the disassociate_srcu lock to be correct. This requires introducing a new lookup mode, UVERBS_LOOKUP_DESTROY as the IOCTL interface needs to hold an unlocked kref until all command verification is completed.
