pinctrl: renesas: Use int type to store negative error codes

[ Upstream commit 9f062fc5b0ff44550088912ab89f9da40226a826 ]

Change the 'ret' variable in sh_pfc_pinconf_group_set() from unsigned
int to int, as it needs to store either negative error codes or zero
returned by sh_pfc_pinconf_set().

No effect on runtime.
