pinctrl: imx: Return NULL if no group is matched and found 

Currently if no group is matched and found, this function will return
the last grp to the caller, this is not expected, it is supposed to
return NULL in this case.

Fixes: e566fc11ea ("pinctrl: imx: use generic pinctrl helpers for managing groups")
