Fix store_read calls
store_read takes a look at the size to determine whether to fill the
provided buffer or not. Even if providing a null buffer we should set
the size to 0.
* defpager/defpager.c (pager_read_page): Initialize nread to 0.
* storeio/dev.c (buffered_rw): Initialize amount to 0.
* fatfs/fat.c (fat_read_sblock): Initialize read to the size of the boot
sector. Reuse it as such.
