Ian Abbott b33fc68c26 staging: comedi: cb_pcidas64: Use insn->n in EEPROM insn_read handler
The `insn_read` handler for the EEPROM subdevice (`eeprom_insn_read()`)
currently ignores `insn->n` (the number of samples to be read) and
assumes a single sample is to be read.  But `insn->n` could be 0,
meaning no samples should be read, in which case `data[0]` ought not to
be written.  (The comedi core at least ensures that `data[0]` exists,
but we should not rely on that.)

Follow the usual Comedi guidelines and interpret `insn->n` as the number
of samples to be read, but only read the EEPROM location once and make
`insn->n` copies, as we don't expect the contents of the EEPROM location
to change between readings.
