[SRU][N:gke][PATCH 038/106] net: hns3: Remove io_stop_wc() calls after __iowrite64_copy()

[Tim Whisonant]

From: Jason Gunthorpe <jgg at nvidia.com>

BugLink: https://bugs.launchpad.net/bugs/2117098

Now that the ARM64 arch implementation does the DGH as part of
__iowrite64_copy() there is no reason to open code this in drivers.
