Subject: [PATCH net] qed/qed_sriov: propagate errors from qed_init_run in enable_vf_access

The return value was silently ignored, and not propagated to the caller.

Found by Linux Verification Center (linuxtesting.org) with the SVACE
static analysis tool.

Fixes: 1408cc1fa48c ("qed: Introduce VFs")
Signed-off-by: Daniil Tatianin <d-tatianin@...dex-team.ru>

I'm not familiar enough with the code to know if there's anything we
have to undo here in case qed_init_run returns an error. Any additional
comments are appreciated.
