[U-Boot] [PATCH v2 1/1] fs: fat: avoid useless conversion when calling get_cluster

Parameter size of function get_cluster() is of type unsigned long. It makes no sense to convert actsize to int before passing it to get_cluster as size. Let't use t_off as type of parameter to avoid any type conversion.

getit:

And similar to my last message, this also causes problems on for example socfpga_sr1500.
