opp: Fix error check in dev_pm_opp_attach_genpd()
[ Upstream commit 4ea9496cbc959eb5c78f3e379199aca9ef4e386b ]
dev_pm_domain_attach_by_name() may return NULL in some cases,
so IS_ERR() doesn't meet the requirements. Thus fix it.
Fixes: 6319aee10e53 ("opp: Attach genpds to devices from within OPP core")
