drivers/staging/zcache/zcache-main.c: fix build

Browse source 
flush_dcache_page() takes a page*, not a void*.  It breaks ia64.

Remove this and another unused function.  Warnings remain:

drivers/staging/zcache/zcache-main.c: In function '__check_disable_cleancache':
drivers/staging/zcache/zcache-main.c:1837: warning: return from incompatible pointer type
drivers/staging/zcache/zcache-main.c: In function '__check_disable_frontswap':

drivers/staging/zcache/zcache-main.c: In function '__check_disable_frontswap_ignore_nonactive':
