[PATCH] mmc: sdhci-msm: When dev_pm_opp_of_add_table() returns 0 it's not an error

[Douglas Anderson]

The commit d05a7238fe1c ("mmc: sdhci-msm: Unconditionally call
dev_pm_opp_of_remove_table()") works fine in the case where there is
no OPP table.  However, if there is an OPP table then
dev_pm_opp_of_add_table() will return 0.  Since 0 != -ENODEV then the
"if (ret != -ENODEV)" will evaluate to true and we'll fall into the
error case.  Oops.

Let's fix this.
