crypto: qat - do not ignore errors from enable_vf2pf_comms()

[ Upstream commit 5147f0906d50a9d26f2b8698cd06b5680e9867ff ]

The function adf_dev_init() ignores the error code reported by
enable_vf2pf_comms(). If the latter fails, e.g. the VF is not compatible
with the pf, then the load of the VF driver progresses.
This patch changes adf_dev_init() so that the error code from
enable_vf2pf_comms() is returned to the caller.
