vfio/common: remove spurious warning on vfio_listener_region_del

851d6d1a0f ("vfio/common: remove spurious tpm-crb-cmd misalignment
warning") removed the warning on vfio_listener_region_add() path.

However the same warning also hits on region_del path. Let's remove
it and reword the dynamic trace as this can be called on both
map and unmap path.
