RDMA/hns: Remove unnecessary access right set during INIT2INIT

mainline inclusion
from mainline-v5.11-rc1
commit 29b52027
category: bugfix
bugzilla: 174002
CVE:NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=29b52027ac354f2a0e5c4d17ca1b621a1644949d

----------------------------------------------------------------------

As the qp access right is checked and setted in common function
hns_roce_v2_set_opt_fields(), there is no need to set again for a special
case INIT2INIT.

Fixes: 926a01dc ("RDMA/hns: Add QP operations support for hip08 SoC")
Fixes: 7db82697 ("RDMA/hns: Add support for extended atomic in userspace")
