[PATCH][next] regulator: fix null pointer check on regmap

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The null pointer check on regmap that checks for a dev_get_regmap failure
is currently returning -ENOENT if the regmap succeeded. Fix this by adding
in the missing ! operator.

Addresses-Coverity: ("Dereference after null check")
Fixes: 4fe66d5a62fb ("regulator: Add support for QCOM PMIC VBUS booster")
