efivarfs: Make 'datasize' unsigned long
There's no reason to declare 'datasize' as an int, since the majority of the functions it's passed to expect an unsigned long anyway. Plus, this way we avoid any sign problems during arithmetic. Acked-by: Jeremy Kerr <jeremy.kerr@canonical.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
