The check for src mac address in ibmveth_is_packet_unsupported is wrong.
Commit 6f2275433a2f wanted to shut down messages for loopback packets,
but now suppresses bridged frames, which are accepted by the hypervisor
otherwise bridging won't work at all.

A test program from the rr[0] test suite, vm_readv_writev[1], no
longer works on 5.10-rc1 when compiled as a 32 bit binary and executed
on a 64 bit kernel. The first process_vm_readv call (on line 35) now
fails with EFAULT. I have bisected this to
c3973b401ef2b0b8005f8074a10e96e3ea093823.

If we fail to allocate vmemmap list, we don't keep track of allocated
vmemmap block buf. Hence on section deactivate we skip vmemmap block
buf free. This results in memory leak.
