[PATCH] migration: increase max-bandwidth to 128 MiB/s (1 Gib/s)

[Laurent Vivier]

max-bandwidth is set by default to 32 MiB/s (256 Mib/s)
since 2008 (5bb7910af031c).

Most of the CPUs can dirty memory faster than that now,
and this is clearly a problem with POWER where the page
size is 64 kiB and not 4 KiB.
