Subject: [PATCH 025/115] rocker: do not pollute the namespace

RH-Author: Paolo Bonzini <pbonzini@redhat.com>
RH-MergeRequest: 391: TDX support, including attestation and device assignment
RH-Jira: RHEL-15710 RHEL-20798 RHEL-49728

RH-Commit: [25/115] fc62404804eee1d9d745359f98b4d7528d1c281b (bonzini/rhel-qemu-kvm)

Do not leave the __le* macros defined, in fact do not use them at all.  Fixes a
build failure on Alpine with the TDX patches:

In file included from ../hw/net/rocker/rocker_of_dpa.c:25:
../hw/net/rocker/rocker_hw.h:14:16: error: conflicting types for 'uint64_t'; have '__u64' {aka 'long long unsigned int'}
   14 | #define __le64 uint64_t
      |                ^~~~~~~~
In file included from /usr/include/stdint.h:20,
                 from ../include/qemu/osdep.h:111,
                 from ../hw/net/rocker/rocker_of_dpa.c:17:
/usr/include/bits/alltypes.h:136:25: note: previous declaration of 'uint64_t' with type 'uint64_t' {aka 'long unsigned int'}
  136 | typedef unsigned _Int64 uint64_t;
      |                         ^~~~~~~~

because the Linux headers include a typedef of __leNN.
