[PATCH] staging: slicoss: remove unused members of struct adapter

[David Matlack <matlackdavid@gmail.com>]

Removes two fields from the private "struct adapter".

memorybase      duplicate of slic_regs

memorylength    written once and never read. This field is trivially
                computed with pci_resource_len if it's ever needed in
                the future.

This patch has no noticable effect.

This patch was originally sent here https://lkml.org/lkml/2014/5/6/9 with
my google.com email address. But due to Google's recent change in DMARC
policies, that patchset was silently dropped for at least some users
(including my personal gmail account). So I'm sending it out now with
my gmail.com account. Let me know if this is an issue. Thanks.
