Subject: RDMA/hns: Remove unused parameter udata
Patch-mainline: v5.14-rc1
Git-commit: 69e0a42f3f79b8bcd83b55b3b0eff8d01aa6b57e
References: jsc#SLE-15176
The old version of ib_umem_get() need these udata as a parameter but now
they are unnecessary.
Fixes: c320e527e154 ("IB: Allow calls to ib_umem_get from kernel ULPs")
