rpc: gss: fix a kmap_atomic race in krb5 code
This code is never called from interrupt context; it's always run by either
a user thread or rpciod. So KM_SKB_SUNRPC_DATA is inappropriate here.
Thanks to Aimé Le Rouzic for capturing an oops which showed the kernel
taking an interrupt while we were in this piece of code, resulting in a
nested kmap_atomic(.,KM_SKB_SUNRPC_DATA) call from
xdr_partial_copy_from_skb().
