block: bump BLK_DEF_MAX_SECTORS to 2560
A value of 2560 (1280k) will accommodate a 10-data-disk stripe
write with chunk size 128k. In the testing I've done using
iozone, fio, and aio-stress across a number of different storage
devices, a value of 1280 does not show a big performance
difference from 512, but will hopefully help software RAID
setups using SATA disks, as reported by Christoph.
NOTE: drivers/block/aoe/aoeblk.c sets its own max_hw_sectors_kb to
BLK_DEF_MAX_SECTORS. So, this patch essentially changes aeoblk to
Use a larger maximum sector size, and I did not test this.
