libstore: Detect device-based access overflow
recnum_t is 32bit while offsets are 64bit. We need to detect the
otherwise-silent truncation of the address. This happens here at 2TiB
for 512-byte sectors.
* libstore/device.c (dev_read, dev_write): Return EOVERFLOW on addresses
that are larger than what the device interface can handle.
