pinctrl: fix pinmux_hog_maps when ctrl_dev_name is not set
The ctrl_dev_name is optional for struct pinmux_map assuming that ctrl_dev is set. Without this patch we can get: Unable to handle kernel NULL pointer dereference at virtual address 00000000 ... (pinmux_hog_maps+0xa4/0x20c) (pinctrl_register+0x2a4/0x378) ... Fix this by adding adding a test for map->ctrl_dev. Additionally move the test for map->ctrl_dev earlier to optimize out the loop a bit.
