net: netxen: fix a missing check and an uninitialized use

[ Upstream commit d134e486e831defd26130770181f01dfc6195f7d ]

When netxen_rom_fast_read() fails, "bios" is left uninitialized and may
contain random value, thus should not be used.

The fix ensures that if netxen_rom_fast_read() fails, we return "-EIO".
