[2/4] RDMA/uverbs: Delete the macro uobj_put_obj_read

Commit Message

Yuval Shaia Aug. 28, 2019, 7:41 a.m. UTC

From: Shamir Rabinovitch <[e-mail]>

The macro uobj_put_obj_read assumes an existence of a member with the name
uobject on each HW object. Since this member is about to be delete we
shouldn't use this macro, instead use uobj_put_read and delete
uobj_put_obj_read.
