Manivannan Sadhasivam 3eb241e47d OPP: Fix passing 0 to PTR_ERR in _opp_attach_genpd()

[ Upstream commit d920920f85 ]

If dev_pm_domain_attach_by_name() returns NULL, then 0 will be passed to
PTR_ERR() as reported by the smatch warning below:

drivers/opp/core.c:2456 _opp_attach_genpd() warn: passing zero to 'PTR_ERR'

Fix it by checking for the non-NULL virt_dev pointer before passing it to
PTR_ERR. Otherwise return -ENODEV.
