[PATCH] Adjust EEPROM read timeout for Intel 4965AGN M2

I'm sorry for a very simplistic change but propagating ETIMEODOUT error from
iwn_read_prom_data upwards is still causing kernel panic as iwn_detach assumes
that the device data structure is complete.

I will work on this problem (error handling) in the future, but since time is
scarce it's better to have at least something working than nothing.
