Subject: [PATCH] vhost: bump SPDK_VHOST_IOVS_MAX to 129

Currently we test up to 512KB I/O sizes, and this I/O
size could fragment to 129 IOVs if split on 4KB
boundaries if the buffer start is not 4KB aligned.

This is likely the cause of a recent slew of failures
in the test pool which coincide with updating to
fio 3.3.
