rt2x00: rt2800: convert read_eeprom functions to return an int value
Both the rtt2x00usb_eeprom_read and the ioremap functions are allowed to fail, however their return values are not checked in the read_eeprom functions in the rt2800{pci,usb} drivers. The patch adds the missing checks, and converts all read_eeprom functions to return an int value, so the error values can be propagated up to the 'rt2800_validate_eeprom' function.
