usb: storage: sddr55: fix sloppy typing in sddr55_{read|write}_data()
In sddr55_{read|write}_data(), the address variables are needlessly typed
as *unsigned long* -- which is 32-bit type on the 32-bit arches and 64-bit
type on the 64-bit arches; those variables' value should fit into just 3
command bytes and consists of 10-bit block # (or at least the max block #
seems to be 1023) and 4-/5-bit page # within a block, so 32-bit *unsigned*
*int* type should be more than enough...
