Subject: [PATCH] aoe: suppress compiler warnings

This patch fixes following compiler warnings:

drivers/block/aoe/aoecmd.c: In function ‘aoecmd_ata_rw’:
drivers/block/aoe/aoecmd.c:383:17: warning: variable ‘t’ set but not used [-Wunused-but-set-variable]
struct aoetgt *t;
^
drivers/block/aoe/aoecmd.c: In function ‘resend’:
drivers/block/aoe/aoecmd.c:488:21: warning: variable ‘ah’ set but not used [-Wunused-but-set-variable]
struct aoe_atahdr *ah;
^
drivers/block/aoe/aoedev.c: In function 'user_req':
drivers/block/aoe/aoedev.c:252:174: warning: comparison of distinct pointer types lacks a cast [enabled by default]
lim = min(sizeof(d->gd->disk_name) - (p - d->gd->disk_name), slen);
^
