[PATCH] crypto/dpaa2_sec: use bus device name

[David Marchand <david.marchand@redhat.com>]

dpaa2_sec_dev_init() sets the crypto device name again after
it has been set by rte_cryptodev_pmd_create/allocate().
Overwritting its value could end up as a bug if the cryptodev
library changes the way it calls cryptodev objects.

Besides, there is no need to generate a name for the crypto device
different than the bus device, as there is a 1:1 relation between
those objects.

Reuse the bus device name directly, iow: dpseci.XXX instead of dpsec-XXX.

Note: this is a followup cleanup following Maxime comment, no pressure on
getting this merged for this release.
