leds: sc27xx: Fix return value check in sc27xx_led_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: e081c49e30ec ("leds: Add Spreadtrum SC27xx breathing light controller driver")
