Fix error code to correct pointer type

To return an errno code inside a pointer,
the error code must first be converted to
the correct pointer type.

drivers/media/v4l2-core/v4l2-of.c:
In function 'v4l2_of_alloc_parse_endpoint':
drivers/media/v4l2-core/v4l2-of.c:227:10: warning:
return makes pointer from integer without
a cast [-Wint-conversion]
return -ENOMEM;

drivers/media/v4l2-core/v4l2-of.c:254:9: warning:
return makes pointer from integer without
a cast [-Wint-conversion]
return rval;
