slic_config_get() can fail. Change the return type from void to
int and handle the error in slic_card_init(). So now, instead of
silently failing (and then timing out waiting for the config data),
the driver will fail loudly at request time.

Remove fail_on_bad_eeprom, which was always 0 and thus being used
to ignore incorrect checksumming. This means devices with corrupt
eeprom will now cause the driver to fail.
Since fail_on_bad_eeprom was the last member in use of struct
slic_reg_params, remove that struct altogether.

Rewrite slic_eeprom_cksum() to fix bugs and make readable. This patch
technically has no effect on the user as failed eeprom checksums are
ignored anyway.
The original implementation had the following issues:
1. 2 of the 3 unrolled loops had the following bug:
while ((len -= 32) >= 0) {
[...]
sum += w[15];
w = (u16 *)((ulong) w + 16); /* verify */
}
This processes 32-bytes of data but only increments the word
pointer by 16 bytes. Fixing both of these bugs seems to fix
slic_eeprom_cksum().
2. Non-descriptive variable names, use of unions, and macros that
change local state make the code difficult to read.
3. The checksum loop is unrolled which makes the code harder to
reason about while providing small performance improvement:
- max eeprom length is 0x80 bytes (MAX_EECODE_SIZE), that's
only 0x40 iterations
- checksum is only computed during pci probe(), so not very
often

This patch fixes a use-after-free bug that causes a null pointer
dereference in slic_entry_halt.
Since unregister_netdev() will ultimately call slic_entry_halt (the
net_device ndo_stop() virtual function for this device), we should
call it before freeing the memory used by slic_entry_halt.

As per the TODO file, this patch removes the gratuitous debug
infrastructure. As an extra incentive for removing this code,
the debugfs files are not cleaned up properly. For example, if
register_netdev() fails in slic_entry_probe() then all debugfs
files get left behind, even after the driver module is unloaded.
Touching these files quickly leads to an oops.
