cfq: Suppress compiler warnings about comparisons
This patch does not change any functionality but avoids that gcc reports the following warnings when building with W=1: block/cfq-iosched.c: In function ?cfq_back_seek_max_store?: block/cfq-iosched.c:4741:13: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] if (__data < (MIN)) \ ^ block/cfq-iosched.c:4756:1: note: in expansion of macro ?STORE_FUNCTION? STORE_FUNCTION(cfq_back_seek_max_store, &cfqd->cfq_back_max, 0, UINT_MAX, 0); ^~~~~~~~~~~~~~ block/cfq-iosched.c: In function ?cfq_slice_idle_store?: block/cfq-iosched.c:4741:13: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] if (__data < (MIN)) \ ^ block/cfq-iosched.c:4759:1: note: in expansion of macro ?STORE_FUNCTION? STORE_FUNCTION(cfq_slice_idle_store, &cfqd->cfq_slice_idle, 0, UINT_MAX, 1); ^~~~~~~~~~~~~~ block/cfq-iosched.c: In function ?cfq_group_idle_store?: block/cfq-iosched.c:4741:13: warning...
