RDMA/hfi1: Remove unused non-user-accessible device class

The driver defines two device classes: "hfi1" (mode 0600) and
"hfi1_user" (mode 0666), selected by a user_accessible parameter to
hfi1_cdev_init(). The only caller always passes user_accessible=true,
so the "hfi1" class is registered but never used.

The 0600 class was originally used by the diagnostics UI char device
(hfi1_ui*), but that was removed over 10 years ago in commit
7312f29d8ee5 ("IB/hfi1: Remove UI char device"). The class and the
user_accessible parameter were left behind.

Remove the unused class and the user_accessible parameter.

Now that there's only one class, it might make sense to change its name
from "hfi1_user" to just "hfi1", but not knowing whether userspace would
mind, keep the name as is.
