regulator: stm32-pwr: Fix return value check in stm32_pwr_regulator_probe()
In case of error, the function of_iomap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
Fixes: 6cdae8173f67 ("regulator: Add support for stm32 power regulators")
