regulator: rt4831: Fix return value check in rt4831_regulator_probe()
In case of error, the function dev_get_regmap() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value
check should be replaced with NULL test.
Fixes: 9351ab8b0cb6 ("regulator: rt4831: Adds support for Richtek RT4831 DSV regulator")
