IB/mlx4: Forbid using sysfs to change RoCE pkeys
commit 2b135db3e81301d0452e6aa107349abe67b097d6 upstream.
The pkey mapping for RoCE must remain the default mapping:
VFs:
virtual index 0 = mapped to real index 0 (0xFFFF)
All others indices: mapped to a real pkey index containing an
invalid pkey.
PF:
virtual index i = real index i.
Don't allow users to change these mappings using files found in
sysfs.
Fixes: c1e7e466120b ('IB/mlx4: Add iov directory in sysfs under the ib device')
