[PATCH -next] agp/uninorth: remove set but not used variable 'size'

[Yue Haibing]

From: YueHaibing <yuehaib...@huawei.com>

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/char/agp/uninorth-agp.c: In function 'uninorth_create_gatt_tablei':
drivers/char/agp/uninorth-agp.c:371:6: warning: variable 'size' set but not 
used [-Wunused-but-set-variable]
drivers/char/agp/frontend.c: In function 'agp_find_seg_in_client':
drivers/char/agp/frontend.c:105:6: warning: variable 'num_segments' set but not 
used [-Wunused-but-set-variable]

It's never used since introduction.
