This patch fixes the following sparse error:
drivers/staging/comedi/drivers//ni_pcimio.c:1229:32: warning: incorrect type in assignment (different base types)
drivers/staging/comedi/drivers//ni_pcimio.c:1229:32: expected restricted __be32 [usertype] serial_number
drivers/staging/comedi/drivers//ni_pcimio.c:1229:32: got unsigned int
This is done by introducing a temporary variable which is of type
'__be32' and converting the existing variable to type 'unsigned int'.

That looks fine, thanks!
(On a side note, nothing actually uses serial number, so the code that
reads it from the EEPROM could just be ripped out.)
